2012 Ultimate. I can open my component in Grasshopper, which has the null reference error 1. Solution exception:Object reference not set to an instance of an object,fine. Now I want to debug in Visual Studio, but my modules say no .pdb file only for any .gha,.dll's, and .rhp's found in C:\Users\Nathaniel\AppData\Roaming\McNeel\Rhinoceros\5.0\Plug-ins\Grasshopper (b45a29b1-4343-4035-989e-044e8580d9cf)\0.9.76.0\. The Debug only loads pdb. for symbols in servers and Grasshopper\Libraries, with one exception for Grasshopper.dll which is the only grasshopper component with a .pdb file in the \Mcneel\Rhinoceros...
Where are the .pdb files for all the other components Starling_0.2.gha, C_sawapan_media_x64.dll, Vector.gha, GH_IO.dll...? I'll run off the checklist of what I've tried:
GrasshopperDeveloperSettings turn off COF
made sure Debug Platform Target is 64, as well as Configuration Manager
add reference in Tools>Options>Symbols add reference (pdb.) to file for where the component files are found.
clicked on load symbols, but that doesn't help or save any .pdb's in my symbolcache.
added same location in ProjectProperies>ReferencePath
added same location in RhinoDeveloperSettings Add Folder
Do I not even need these symbols to debug? Is there a way to add .pdb's manually to my symbolcache? Why does my breakpoint say The debugger could not locate the source file 'C:\dev\grasshopper\1.0\root\src\GH_Component.vb'? I think I read that Grasshopper was written in .vb..Why does my callstack say Grasshopper.dll!Grasshopper.Kernel.GH_Component.New(String name, String nickname, String description, String category, String subCategory)? Why the ! after the .dll?
I am thankful for any input

mages, output from Radiance (or not necessarily in my case, but processed using Radiance/pcomb).
Has anyone tried to apply bespoke or unusual gradient palettes to their false-colour images ?
It would be so great to be able to process images like grids, using a preset library much like this:
https://github.com/mostaphaRoudsari/ladybug/blob/master/resources/gradients.jpg
I used to use the 5 available palettes described in A. Jacob's Radiance Cookbook (+ bespoke ones) on the command line with the old falsecolor.pl , but I don't think these are available now with falsecolor2.exe... am I right?
I am aware of the alternative old palette -spec but in the current HB false-colour component, but is that it ?
Another question for Mingbo - I get the following error message when trying to open the attached HDR file with your amazing new viewer: 1. Solution exception:Parameter is not valid.
Am I doing anything wrong ? I can see many useful applications to your pixel-value reader, especially if externally rendered HDR images can be loaded (which is the case here). Do they need a specific header to be "valid" ?
Many thanks in advance for your help.
Best,
Jocelyn

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

ion of both Ladybug and Honeybee. Notable among the new components are 51 new Honeybee components for setting up and running energy simulations and 15 new Ladybug components for running detailed comfort analyses. We are also happy to announce the start of comprehensive tutorial series on how to use the components and the first one on getting started with Ladybug can be found here:
https://www.youtube.com/playlist?list=PLruLh1AdY-Sj_XGz3kzHUoWmpWDXNep1O
A second one on how to use the new Ladybug comfort components can be found here:
https://www.youtube.com/playlist?list=PLruLh1AdY-Sho45_D4BV1HKcIz7oVmZ8v
Here is a short list highlighting some of the capabilities of this current Honeybee release:
1) Run EnergyPlus and OpenStudio Simulations - A couple of components to export your HBZones into IDF or OSM files and run energy simulations right from the grasshopper window! Also included are several components for adjusting the parameters of the simulations and requesting a wide range of possible outputs.
2) Assign EnergyPlus Constructions - A set of components that allow you to assign constructions from the OpenStudio library to your Honeybee objects. This also includes components for searching through the OpenStudio construction/material library and components to create your own constructions and materials.
3) Assign EnergyPlus Schedules and Loads - A set of components for assigning schedules and Loads from the Openstudio library to your Honeybee zones. This includes the ability to auto-assign these based on your program or to tweak individual values. You can even create your own schedules from a stream of 8760 values with the new “Create CSV Schedule” component. Lastly, there is a component for converting any E+ schedule to 8760 values, which you can then visualize with the standard Ladybug components
4) Assign HVAC Systems - A set of components for assigning some basic ASHRAE HVAC systems that can be run with the Export to OpenStudio component. You can even adjust the parameters of these systems right in Grasshopper.
Note: The ASHRAE systems are only available for OpenStudio and can’t be used with Honeybee’s EnergyPlus component. Also, only ideal air, VAV and PTHP systems are currently available but more will be on their way soon!
5) Import And Visualize EnergyPlus Results - A set of components to import numerical EnergyPlus simulation results back into grasshopper such that they can be visualized with any of the standard Ladybug components (ie. the 3D chart or Psychrometric chart). Importers are made for zone-level results as well as surface results and surfaces results can be easily separated based on surface type. This also means that E+ results can be analyzed with the new Ladybug comfort calculator components and used in shade or natural ventilation studies. Lastly, there are a set of components for coloring zone/surface geometry with EnergyPlus results and for coloring the shades around zones with shade desirability.
6) Increased Radiance and Daysim Capabilities - Several updates have also been made to the existing Radiance and Daysim components including parallel Radiance Image-based analysis.
7) Visualize HBObject Attributes - A few components have been added to assist with setting up honeybee objects and ensuing the the correct properties have been assigned. These include components to separate surfaces based on boundary condition and components to label surfaces and zones with virtually any of their EnergyPlus or Radiance attributes.
8) WIP Grizzly Bear gbxml Exporter - Lastly, the release includes an WIP version of the Grizzly Bear gbXML exporter, which will continue to be developed over the next few months.
And here’s a list of the new Ladybug capabilities:
1) Comfort Models - Three comfort models that have been translated to python for your use in GH: PMV, Adaptive, and Outdoor (UTCI). Each of these models has a “Comfort Calculator” component for which you can input parameters like temperature and wind speed to get out comfort metrics. These can be used in conjunction with EPW data or EnergyPlus results to calculate comfort for every hour of the year.
2) Ladybug Psychrometric Chart - A new interactive psychrometric chart that was made possible thanks to the releasing of the Berkely Center for the Built Environment Comfort Tool Code (https://github.com/CenterForTheBuiltEnvironment/comfort-tool). The new psychrometric chart allows you to move the comfort polygon around based on PMV comfort metrics, plot EPW or EnergyPlus results on the psych chart, and see how many hours are made comfortable in each case. The component also allows you to plot polygons representing passive building strategies (like internal heat gain or evaporative cooling), which will adjust dynamically with the comfort polygon and are based on the strategies included in Climate Consultant.
3) Solar Adjusted MRT and Outdoor Shade Evaluator - A component has been added to allow you to account for shortwave solar radiation in comfort studies by adjusting Mean Radiant Temperature. This adjusted MRT can then be factored into outdoor comfort studies and used with an new Ladybug Comfort Shade Benefit Evaluator to design outdoor shades and awnings.
4) Wind Speed - Two new components for visualizing wind profile curves and calculating wind speed at particular heights. These allow users to translate EPW wind speed from the meteorological station to the terrain type and height above ground for their site. They will also help inform the CFD simulations that will be coming in later releases.
5) Sky Color Visualizer - A component has been added that allows you to visualize a clear sky for any hour of the year in order to get a sense of the sky qualities and understand light conditions in periods before or after sunset.
Ready to Start?
Here is what you will need to do:
Download Honeybee and Ladybug from the same link here. Make sure that you remove any old version of Ladybug and Honeybee if you have one, as mentioned on the Ladybug group page.
You will also need to install RADIANCE, DAYSIM and ENERGYPLUS on your system. We already sent a video about how to get RADIANCE and Daysim installed (link). You can download EnergyPlus 8.1 for Windows from the DOE website (http://apps1.eere.energy.gov/buildings/energyplus/?utm_source=EnergyPlus&utm_medium=redirect&utm_campaign=EnergyPlus%2Bredirect%2B1).
“EnergyPlus is a whole building energy simulation program that engineers, architects, and researchers use to model energy and water use in buildings.”
“OpenStudio is a cross-platform (Windows, Mac, and Linux) collection of software tools to support whole building energy modeling using EnergyPlus and advanced daylight analysis using Radiance.”
Make sure that you install ENERGYPLUS in a folder with no spaces in the file path (e.g. “C:\Program Files” has a space between “Program” and “Files”). A good option for each is C:\EnergyPlusV8-1-0, which is usually the default locations when you run the downloaded installer.
New Example Files!
We have put together a large number of new updated example files and you should use these to get yourself started. You can download them from the link on the group page.
New Developers:
Since the last release, we have had several new members join the Ladybug + Honeybee developer team:
Chien Si Harriman - Chien Si has contributed a large amount of code and new components in the OpenStudio workflow including components to add ASHRAE HVAC systems into your energy models and adjust their parameters. He is also the author of the Grizzly Bear gbxml exporter and will be continuing work on this in the following months.
Trygve Wastvedt - Trygve has contributed a core set of functions that were used to make the new Ladybug Colored Sky Visualizer and have also helped sync the Ladybug Sunpath to give sun positions for the current year of 2014
Abraham Yezioro - Abraham has contributed an awesome new bioclimatic chart for comfort analyses, which, despite its presence in the WIP tab, is nearly complete!
Djordje Spasic - Djordje has contributed a number of core functions that were used to make the new Ladybug Wind Speed Calculator and Wind Profile Visualizer components and will be assisting with workflows to process CFD results in the future. He also has some more outdoor comfort metrics in the works.
Andrew Heumann - Andrew contributed an endlessly useful list item selector, which can adjust based on the input list, and has multiple applications throughout Ladybug and Honeybee. One of the best is for selecting zone-level programs after selecting an overall building program.
Alex Jacobson - Alex also assisted with the coding of the wind speed components.
And, as always, a special thanks goes to all of our awesome users who tested the new components through their several iterations. Special thanks goes to Daniel, Michal, Francisco, and Agus for their continuous support. Thanks again for all the support, great suggestions and comments. We really cannot thank you enough.
Enjoy!,
Ladybug + Honeybee Development Team

I am starting to wonder if I have some sort of mismatch between my GHA file and my Diva version, though I'm not sure that would cause these kinds of problems.
Incidentally, I tried creating a brand new file and I get the same results. I cannot save anything with DIVA components in them, they disappear every time. :(
Speaking of 2.0, do you happen to know when that will be released?
Thanks,
Marc

Hello Patricio, divide the beams in such a way that each boundary vertex of the shell becomes an endpoint of a beam segment.

Hi Clemens,
I did what you suggested but now assemble element doesn´t work properly. Could you please tell me how to fix it? Thanks in advance, Patricio

Comment by karamba on October 8, 2014 at 11:59am
Hi Patricio, if you flatten the 'Elem'-input at the 'Assemble'-component the definition works. The triangular shell elements have linear displacement interpolations whereas the beam deflections are exact. In order to get correct results you should refine the shell mesh.
Best, Clemens

Hello, succeeds in creating the mesh to the slab, and built the beam segment, but when I see the deformations are not expected because the beam is deformed as the slab.
Thanks for the help
PS: maybe I'm using the program for a type of structure that is not the most appropriate, as I saw in the examples of other structures. But this type of structure is that students taught
best regards
Patricio

Comment by karamba on October 9, 2014 at 10:46am
You could use the 'Mesh Edges'-component to retrieve the naked edges and turn them into beams - see attached file:91014Example1_cp.gh
Best regards,
Clemens

Dear clemens
I was doing a rough estimate of the deformation, and I can not achieve the same result with Karamba. When I make a rough estimate of the result with Karamba beams and mine are very similar, I think the problem is when I connect the shell, because there are no similar results.
I sent the GH file, and an image of the calculation
The structure is concrete The result I get is 0.58cm
thank youPatricio

Dear Patricio,
try to increase the number of shell elements. As mentioned in the manual they are linear elements. A mesh that is too coarse leads to a response which is stiffer than the real structure.

…
th the most crucial and imposing challenges that Mexico City faces and the ways in which architecture and urbanism can shape the metropolis at different scales. In these sense the progamme sees the city as a laboratory where the virtual and experimental tradition of the Architectural Association finds a fertile and concrete ground for the application of its methodology in Mexico.
“Manufactured Landscapes/Manufactured Urbanities” explores the metropolitan condition understood as a manufactured process by and for human beings. Henceforth the traditional opposing concepts, artificial vs nature, are replaced under the premise, nature does not exist, where nature is not natural but naturalised and the artificial is not an external or impose construct but manufactured intrinsically.
With this as a starting point the programme will study 2 instances of Mexico City’s “Manufactured Landscapes/Manufactured Urbanities”: The ravines in the west of Mexico City, last bastion of the existing “Nature” and its crucial role in the viability of Mexico City and social housing, as the fundamental construct of the “artificial” habitat in the metropolis´s urban tissue. These “Manufactured Landscapes/Manufactured Urbanities” and the ways in which they are designed, produced, reinvented regenerated, show a vast spectrum representative of the crucial urban conditions to be address and therefore they posed an enormous urban and architectonic challenge to confront in order to apply contemporary design methodologies.
To tackle the complexities of the “Manufactured Landscapes/Manufactured Urbanities”, the programme will immerse students and staff in a 10 day intensive workshop within a multidisciplinary environment where national and international experts from various fields will enrich their proposals. Students will work in architecture and/or urban scale teams and will critically assess the impact of their multiple scales interventions.
A backbone of lectures, talks and seminars, including local and international speakers, are designed to broaden and reflect the relevance and the importance of the topic for Mexico City. Finally a public exhibition of student’s work will be held at Centro Cultural de España in autumn 2013.
