n be obtained for curved NURBS surfaces as well as unconventional window configurations".
And I also noticed the following information form the optional input in the runEnergySimulation component.
"meshSettings_: Optional mesh settings for your geometry from any one of the native Grasshopper mesh setting components. These will be used to change the meshing of curved surfaces before they are run through EnergyPlus (note that meshing of curved surfaces is done since Energyplus is not able to calculate heat flow through non-planar surfaces). Default Grasshopper meshing is used if nothing is input here but you may want to decrease your calculation time by changing it to Coarse or increase your curvature definition (and calculation time) by making it finer".
1) My case is an one-story, rectangular-plan large hall (40m*70m*25m) with a curved roof. The roof surface is a part of a standard sphere and the walls and floor are all planar (the each wall has one curved edge as showed in the image).
For testing, I threw the original curved roof surface into daylight and energy simulations without making customized meshings, because I assumed that it might be automatically converted to meshs by Honeybee - Am I right? As showed in the image, how can I reduce the number of meshs in a proper way? Must two connected surfaces (i.e. wall and roof) be STRICTLY/SEAMLESSLY connected or not (considering different divisions of meshs in the respective surface)? - Is a connection tolerance allowed?
2) But, when I run the annual daylight simulation for this case, it gave me a lot of warnings "oconv: warning - zero area for polygon".- is that normal? and how to avoid this? Does the daylight simulation allow "curved NURBS surfaces"?
3) Moreover, when I run an energy simulation for this case, it costed extremely long time. It was just so long that I did not even have results out of one simulation. - I guessed it might be the problem caused by the curved roof surface (or automatic meshing?), but I don't have experience of converting a curved NURBS/spheral surface into correct meshs that can be recognized by Honeybee simulations (Daylight and Energy) in a proper way.
4) The large window on the wall was generated by the "_glzRatio". But the automatically generated wall meshs around this window are just too "fine", which might largely increase simulation time. Is there a proper way to get rid of it? (Considering that the size, shape and position of the window will have large influence on the daylight distribution in the building, it is worthy to keep the size, shape and position of the window as it should be in reality).
In sum, considering all above, could your please provide me some suggestions/tutorials/links that might be helpful for dealing with "curved NURBS surfaces" in Honeybee simulations.
Thank you all in advance!
Best,
Ding

Karamba.
I am using your plug-in for normal forces evaluation in the transvere wires and spreaders of a sailboat. Mast is solved in another way, so I am not taking forces from Karamba in that case.
Basing on the forces value an adequate wire size (diameter) is choosen. Then masses of wires are being calculated. Loads (forces) on longitudinal wires are calculated without Karamba. The problem is when choosing transverse wires’ mass minimization as a criteria, the Octopus doesn’t get any results - is changing the sliders (genes) too fast for Karamba to calculate the forces (so Octopus gets only nulls):
When minimization of a e.g. longitudinal wires’ mass (calculated without Karamba) is taken as a criteria Octopus works fine.
Which suggests that the problem is in interaction of two plug-ins.
Any ideas how to avoid that problem?
Thanks,
M.

Despite the ‘orange warning’ the values are correct (double checked with other software).However I don't know why does it say that there is a part that can move freely without deformation,as the model looks like this:

er). With the command "End Bulge" I noticed that G2 moves perpendicular to G1! But with an increase which is not equal... and is different, every time, depending on the angle between G0 and G1 and G2. How do I predict the position of G2 compared to G1 simulating the "End Bulge" command? Thank you for your professional answers.
^___^
Below you can see an example with a curve crimson ... If I move G1 of 1 unit G2 moves of 0.42 units (perpendicular) .. If I move of 2 units the next step is 0.46 unit... 3 units --> step 0,50 units... etc.
And each time changes depending on the initial conditions (G0/G1/G2 angle).

or GH with: 1. Animation Timeline 2. Rendering 3. API
Summary:
Animation Timeline: Smooth animation system that plays at the real-world speed; so you know the robot will run just right when you upload the code.
Rendering: Extensive options and outputs; so you can generate amazing videos.
API: Access our functions through Python and C# scripting; so you can manage parameters and actions for complex processes for each target.
More info:
Animation Timeline:
Build an animation from a list of Planes, it's that easy! Get these from points, curves or surfaces. Download the example files with the trial and test it yourself.
The unique Timeline component displays all the important robot warnings and the digital Input/Ouput:
RED – clash detection BLUE - singularities YELLOW – over rotation ORANGE – out of reach Digital Inut/Output: red=off, green=on
Rendering:
IO smoothly interpolates between all the Planes you set. This means you can generate keyframes for positions between Planes too e.g. you have two planes defining a tool path, IO can generate 2000 keyframes. Smooooth!
Rendered in full colour as standard, not GH red :-)
LiveBaking - let's you use Rhino render settings in real-time (can be a bit slow!)
Slider animation - use the native 'Animate' option to export hi-res images and create videos easily. Just set the number of frames you need (hint: divide total time in seconds by the frames-per-second rate)
Bake unlimited meshes as keyframes for export to render-pipelines in 3DS etc.
API
Accessing the IO functions through Python and C# let's you build more powerful definitions. You can assign data to every position the robot reaches, allowing you to control speed, acceleration, wait-times, actions and more. Examples comparing C# with Python are included in the examples files.
You can also use teh API build your own plugins that use the IO timeline to do all the hard work like IK and creating valid code, while you enjoy developing your new process...
Check out the website for more features and videos of the example definitions: www.robots.io

t. So here we go!
1. Honeybee is brown and not yellow [stupid!]...
As you probably remember Honeybee logo was initially yellow because of my ignorance about Honeybees. With the help of our Honeybee expert, Michalina, now the color is corrected. I promised her to update everyone about this. Below are photos of her working on the honeybee logo and the results of her study.
If you think I'm exaggerating by calling her a honeybee expert you better watch this video:
Thank you Michalina for the great work! :). I corrected the colors. No yellow anymore. The only yellow arrows represent sun rays and not the honeybee!
2. Yellow or brown, W[here]TH Honeybee is?
I know. It has been a long time after I posted the initial video and it is not fun at all to wait for a long time. Here is the good news. If you are following the Facebook page you probably now that the Daylighting components are almost ready.
Couple of friends from Grasshopper community and RADIANCE community has been helping me with testing/debugging the components. I still think/hope to release the daylighting components at some point in January before Ladybug gets one year old.
There have been multiple changes. I finally feel that the current version of Honeybee is simple enough for non-expert users to start running initial studies and flexible enough for advanced users to run advanced studies. I will post a video soon and walk you through different components.
I think I still need more time to modify the energy simulation components so they are not going to be part of the next release. Unfortunately, there are so many ways to set up and run a wrong energy simulation and I really don’t want to add one new GIGO app to the world of simulation. We already have enough of that. Moreover I’m still not quite happy with the workflow. Please bear with me for few more months and then we can all celebrate!
I recently tested the idea of connecting Grasshopper to OpenStudio by using OpenStudio API successfully. If nothing else, I really want to release the EnergyPlus components so I can concentrate on Grasshopper > OpenStudio development which I personally think is the best approach.
3. What about wind analysis?
I have been asked multiple times that if Ladybug will have a component for wind study. The short answer is YES! I have been working with EFRI-PULSE project during the last year to develop a free and open source web-based CFD simulation platform for outdoor analysis.
We had a very good progress so far and our rockstar Stefan recently presented the results of the work at the American Physical Society’s 66th annual DFD meeting and the results looks pretty convincing in comparison to measured data. Here is an image from the presentation. All the credits go to Stefan Gracik and EFRI-PULSE project.
The project will go live at some point next year and after that I will release the Butterfly which will let you prepare the model for the CFD simulation and send it to EFRI-PULSE project. I haven’t tried to run the simulations locally yet but I’m considering that as a further development. Here is how the component and the logo looks like right now.
4. Teaching resources
It has been almost 11 months from the first public release of Ladybug. I know that I didn't do a good job in providing enough tutorials/teaching materials and I know that I won’t be able to put something comprehensive together soon.
Fortunately, ladybug has been flying in multiple schools during the last year. Several design, engineering and consultant firms are using it and it has been thought in several workshops. As I checked with multiple of you, almost everyone told me that they will be happy to share their teaching materials; hence I started the teaching resources page. Please share your materials on the page. They can be in any format and any language. Thanks in advance!
I hope you enjoyed/are enjoying/will enjoy the longest night of the year. Happy Yalda!
Cheers,
-Mostapha

y anyway ;))
Since 2014 i begun to get back into the construction biz for some dozen main reasons, one of them being the highly increased availability of this kind of software "power", and robotics.
first project ended by 1stQ 2015 was focused on the development of a parametric block for construction. (almost sure the first parametric product designed in Uruguay, and probably one of the few first of this kind globally...)
Far from being a complicated model. In fact the standard model is extremely simple, key thing is that is fully parametric...
dimensions, materials, textures, colors... and so on
second key thing is that the main common component of the blocks (an EPS core) is robotically machined...
the blocks are the base of a construction system (oriented mainly - though not restricted only - to residential buildings) that
- is based on digital models, tendentially to be used in parametric models of buidings
- lab tested to prove to be 1.5 times as compression resistant than traditional bricks and blocks. (autoportability up to two stories buildings)
- has recently proved (due to size) to be 300% more efficient than the classic and 200% more efficient than steel frame in (our country official figures)
check it out here

- and it's aimed to be mass produced and handled by robots...
this project ended on 1H 2016
and i filed 4 patents in the process.
3 of them of mechanical devices designed as extensions for a cnc machine i own
and the fourth (
the patent related specifically with the blocks ) included a dozen of innovations (believe me...i have almost 15 yrs in the biz, and are coool stuff...)
along the project I've been working with inventor, even knowing in advance it will lack the kind of features I wanted to program many things... (lisp, VB, etc.... all same species of -prehistoric - animals) to leverage the tool to the sky - and far beyond... -
but was an alternative valid by that time because it allows the implementation of some form of parametric models, had a local representative and some supposedly skilled guys in the neibourhood....
but life is hard... and none of the latter two rendered me any significant help
so I had to take the tour myself...
- mind i never regret to do things that others cant -
and finish what i start
this one was a great project for many figures... and ended with more results than the ones commited to accomplish...
... some more history here ....
then because of a customer who brought a ZHA project ! to quote..., I crossed with rhino, and then met GH again to notice to my great joy and pleasure, in what kind of animal it had developed...
since money talks I'm investing hard on getting up to the expectations, and beyond as i usually do...
and thats how we met..
2017-2018 it's the time frame to build two robots. first one is a prototype to handle the k-nano blocks in the production process, delivery AND at the construction site ( a "smart crane" we nicknamed...)
the other one is the first prototype of robot to assist in the fabrication (smart blocker we called it to be creative ! ;))
then by 2018-2019 i'll be making a "kinda contour crafter" machine to complete the pie :) (you'll be interested on this..)
i guess you already know what all this has to do with GH...
i already have all the components i can imagine to do almost all i ever wanted to do in relation to this set of projects
but in almost a single tool !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
i can design, animate, render, optimize, simulate and even robotic simulate..
so, i have to ask...
is there a chance you might be interested in helping us in some projects we are starting on march and june 2017 (8 and no more than 18 months of duration respectively) ?
sent you a friend request, for the case you might be interested to continue by e-mail...
in any case many thanks for your help and inspiration !
best regards !
long happy marriage, and large figures bank account !
…
or a couple of thingies.
Pattern.gh
I defined parametrically a triangle which I then smoothed out to become more like a blob shape. After that I created a pretty simple pattern that I had in my mind (costed me a lot of time to make this in GH) and finally wanted to rotate each element as it goes higher . The dispatching part seems to be working pretty slow, so it might need an optimization, but I’m still happy with the result as it shows exactly what I wanted, so this is a minor issue in my case.
I then decided to try tessellating my extrusions. You’ll see the voronoi script which is a blob-group in the same Pattern.gh:
I had an idea of something and started the code from scratch, then decided to watch tutorials and implement the code shown there. I somehow coped to combine my code with this in the tutorials, but since my knowledge of Grasshopper is zero to basic my code seems to be very unoptimized and lagging.. When dragging the sliders, it takes a lot of time to compute the changes, although, I’m working on a 24gigs 6th gen i7 machine. It might also need optimization.
Here comes the first tricky part that I couldn’t sort out in an elegant way neither in Grasshopper nor in Rhino. I want a smooth transition between the wall and the ceiling, so that the voronoi tessellation doesn’t get interrupted. If I was to do it in Rhino I’d make a curve with a filleted edge which I’d then revolve/sweep along a rail.
Pattern.gh:
Second thing is – I’ve defined a shape which I want to rotate at a certain degree as it goes higher, however, I don’t have the knowledge to make this happen automatically and just copy the script over and over again. Is there a chance to somehow “loop” the code and parametrically define the degree of rotation and amount of units in the loop?
Next thing is I want to somehow be able to rotate each “6-storey-building” dependently on its surrounding buildings, so that their “terraces” never overlap. I’m using quotes, since they’re still some silly shapes that have nothing to do with buildings and terraces. The principle has to be something like gear wheels or the so-called rack wheels . There has to be some pace which I could set parametrically, but I’m still unsure how to do that in Grasshopper.
The pre-last thing is that I want to control the height of each “building” based on let’s say a topography. I presume this could be done somehow with height maps or some gradient mapper connected to curvature analysis. Not really sure how something like this would work, but I’ve seen such codes that control height depending on a variable.
The last one is more or less similar to the previous. I want to be able to “dissolve” the pattern that I initially created and make it irregular. I suppose this could be done with attractor curve, but again this is just a guess. Please note that this is a top view and the shapes on the upper-left corner have got more "wings" which means there is more floors in the according building. Let's say the buildings in the upper-left corner are 6-7 floors high, in the middle are 4-5 and to the right they're only 3 floors high.
Sorry for that many questions in a single thread. Please let me know if I have to split them in separate threads. All this information is needed for learning purposes. I’m now preparing myself for my bachelor thesis and try as much things as I could, so that I’ll be ready for the final stage of my bachelor’s degree.
Many thanks in advance! Cheers!…
the results myself and I am open to changing the name/description of the input based on what you have found here. modulateFlowOrTemp is not the best name for what seems to be going on and we should change it to reflect more what is happening in the IDF.
Here is how I am understanding the results of the different cases:
1) When the variable flow option is selected (and the outdoor air set to "None"), the heating and cooling of the space seems to happen only through re-circulation of the indoor air. My comparison to a VAV system was not appropriate and perhaps it would be better to compare it to a window air conditioner or a warm air furnace, which, as far as I understand, only re-circulate indoor air and do not bring in outside air.
2) My reasoning for the name modulateFlowOrTemp came mostly from my realization that the supply air temperature remained within the defined limits when the variable flow option is selected (and the outdoor air set to "None"). When the outdoor air was set to Maximum or Sum, the supply air temperature went way out of the temperature limits that I initially set. I realize now that the flows are varying in both cases and the name of the input really must change.
3) I think that the reason why we don't see any effect from the air side economizer is because the heating/cooling energy results that you get from an ideal air system are just the sum of the sensible and the latent heat added/removed from the zone by the system. This value of heat added or removed from the zone does not change whether the added/removed heat comes from outside air or from a cooling/heating coil. Since there is no cooling coil or boiler or chiller in an ideal air system, there is no way to request an output of the energy added/removed by such a coil or chiller as opposed to that removed/added by outside air. In other words, the air side economizer option on the ideal air system is practically useless because it does not help us differentiate the cooling that comes from the outside air vs. that which comes from a coil. All that it does is change the outdoor air fraction while keeping the reported cooling/heating values the same.
Please let me know if you think that this explanation makes sense, Burin and, in light of all this, I am very interested in your suggestions.
From my own perspective, I am now convinced that the default should definitely have the outside air requirements set to "None" since, otherwise, we cannot distinguish cooling/heating that happens from addition of outside air and that which must be supplied by a coil. At least when we get rid of the outside air requirement, we can be sure that the ideal air system values are only showing heating/cooling from a coil or HVAC system.
I have decided to remove the airsideEconomizer input since it seems to give misleading expectations. I am going to recommend here on out that, if you want to estimate the effect of increasing outside air on cooling, you should use the "Set EP Airflow" component, use fan-driven natural ventilation, and you should connect a custom CSV schedule of airflow. You will have to create such a schedule with native GH components using the outside air temperature, your zone setpoints, and the times that you are cooling in your initial run of E+. Either you do this or you set up a full-blown system with OpenStudio.
I have also decided to get rid of the heatRecovery input since it seems like this will also produce misleading expectations by the same logic.
Lastly, I am going to change the name of the modulateFlowOrTemp_ input to outdoorAirReq_. The default will be to have no indoor air requirement as stated above but you can input either "maximum" or "sum" to have the IDF run accordingly.
Let me know if this sounds good or if you have suggestions. Updated GH file attached. The github has the new Ideal Air Loads component. Make sure that you have sync correctly and restart GH after updating your components.

the data structure of the input.
I'll create a component that aims to write all the GH_Paths inside the input data structure into separate output parameters. I'll add a menu item to the component that allows users to synch the number of outputs with the current data.
Note that there are some bugs I found related to Undo here, but I'll attempt to fix those asap. The mechanisms employed in this example are correct.
Let's start with the Component class definition and the constructor:
Public Class GH_ExampleComponent_VarOutput
Inherits GH_Component
Public Sub New()
MyBase.New("Extract Paths", "ExPath", "Extract all the paths from a tree", "Sets", "Tree")
End Sub
End Class
Now, the RegisterXXXXParams methods:
Protected Overrides Sub RegisterInputParams(ByVal pManager As GH_Component.GH_InputParamManager)
pManager.Register_GenericParam("Tree", "T", "Data tree to examine", GH_ParamAccess.tree)
End Sub
Protected Overrides Sub RegisterOutputParams(ByVal pManager As GH_Component.GH_OutputParamManager)
'We'll add one output parameter, just to not have a jagged output.
pManager.Register_PathParam("Path 1", "1", "1st path in tree")
End Sub
SolveInstance() is somewhat special, but not very complicated:
Protected Overrides Sub SolveInstance(ByVal DA As IGH_DataAccess)
'We have only one input parameter and it is set to Tree,
'so SolveInstance will only be called once for every solution.
'We don't actually need the data inside the input, we're only interested in the paths.
'So we don't actually need to call DA.GetDataTree, we can just go in and extract the
'paths directly:
Dim paths As IList(Of GH_Path) = Params.Input(0).VolatileData.Paths
'Abort if there is no tree.
If (paths.Count = 0) Then Return
'Post a warning if the number of output parameters does not
'equal the number of paths in the tree.
If (paths.Count < Params.Output.Count) Then
AddRuntimeMessage(GH_RuntimeMessageLevel.Warning, "There are more outputs than paths in the tree.")
ElseIf (paths.Count > Params.Output.Count) Then
AddRuntimeMessage(GH_RuntimeMessageLevel.Warning, "There are fewer outputs than paths in the tree.")
End If
'Iterate over all paths and assign to output parameters.
For i As Int32 = 0 To Math.Min(Params.Output.Count, paths.Count) - 1
DA.SetData(i, paths(i))
Next
End Sub
Adding a menu item to the component menu is relatively straightforward, however handling the menu command requires a fair bit of logic:
Protected Overrides Sub Menu_AppendCustomComponentItems(ByVal iMenu As System.Windows.Forms.ToolStripDropDown)
'Add a single item to the component menu.
Menu_AppendGenericMenuItem(iMenu, "Synch outputs", AddressOf Menu_SynchOutputClicked)
End Sub
Private Sub Menu_SynchOutputClicked(ByVal sender As Object, ByVal e As EventArgs)
'Here we have to synch the number of output parameters with the number
'of paths in the volatile data tree in the input parameter.
'This requires a few steps:
'1. Determine whether something needs to happen at all.
'2. Record an undo event.
'3. Remove excess outputs or add missing outputs.
Dim paths As IList(Of GH_Path) = Params.Input(0).VolatileData.Paths
If (paths.Count = Params.Output.Count) Then Return 'yay, nothing needs to be done.
'Something needs to be done, record an undo state.
RecordUndoEvent("Synch output")
'We either have too few or too many outputs, determine which is the case.
If (paths.Count > Params.Output.Count) Then
'Add the missing outputs
For i As Int32 = Params.Output.Count + 1 To paths.Count
Dim param As New Grasshopper.Kernel.Parameters.Param_GenericObject()
param.Name = "Path " & i.ToString()
param.NickName = i.ToString()
If (i.ToString.EndsWith("1")) Then
param.Description = i.ToString() & "st path in tree"
ElseIf (i.ToString.EndsWith("2")) Then
param.Description = i.ToString() & "nd path in tree"
ElseIf (i.ToString.EndsWith("3")) Then
param.Description = i.ToString() & "rd path in tree"
Else
param.Description = i.ToString() & "th path in tree"
End If
Params.RegisterOutputParam(param)
Next
Else
'Remove excessive outputs
Do
If (Params.Output.Count <= paths.Count) Then Exit Do
Dim param As IGH_Param = Params.Output(Params.Output.Count - 1)
Params.UnregisterOutputParameter(param)
Loop
End If
Params.OnParametersChanged()
ExpireSolution(True)
End Sub
Finally, we must make sure that the component properly (de)serializes. This means we have to override the Write and Read methods and add additional information to the GHX archive:
Public Overrides Function Write(ByVal writer As GH_IO.Serialization.GH_IWriter) As Boolean
'We must make sure that the number of output parameters is correctly stored.
'We'll use a special function on the GH_ComponentParamServer to accompish this
'without too much sweat.
Params.WriteParameterTypeData(writer)
Return MyBase.Write(writer)
End Function
Public Overrides Function Read(ByVal reader As GH_IO.Serialization.GH_IReader) As Boolean
'Very important, we must make sure all parameters exist before we
'start with the main deserialization.
Params.Clear()
Params.ReadParameterTypeData(reader)
Return MyBase.Read(reader)
End Function
I attached a VB file that contains the code outlined above.
