vid Rutten (the creator of Grasshopper) as the leading poster. Amassing just over 7000 posts. I have been a regular contributor since this forum starter 5 years ago and I am only half way there.
The line between "the only stupid question is the unasked question" and the "why is no one here answering my questions question" needs to be walked with care.
We have all been where you are now. Admittedly it was probably easier for me as there wasn't that much to the program when I started using it and my learning curve has been an incremental one as things get added.
It doesn't help that all the documentation that is around is out of date as soon as it gets published, but that is the nature of software in BETA... things change. I know of a concerted effort by the powers to be to document Grasshopper better. But this is a little way of from completion.
If it helps I can think of two examples of questions that I either should have asked or did and regretted.
Firstly I had no idea you could bake geometry into the rhino document when I first used Explicit History (former name of GH) I mean what the hell does a fried egg have to do with it :) so I simply ignored the plug-in for a month or so. If I'd asked how do I get my Red transparent surfaces into Rhino, I would have been using it a lot sooner.
Secondly I wished for a way to display the output of a component so that I could see it without having to hover over the tool tip each time. I didn't realise that Post-it Note (or Panel as it is now due to copyright issues) had an input as well as an output.
The most important thing to remember is that Grasshopper is an extension of Rhino. By not knowing Rhino you are at a greater disadvantage than the rest.
If you don't know how you should go about modelling something in Rhino how are you going to be able to develop meaningful algorithms in Grasshopper.

sistance of radiative and convective heat transfer through the _filmCoefficient input on the "Create Therm Boundaries" component. This filmCoefficient in W/m2K represents the "U-Value" of the air film between the edge of the THERM materials and the surrounding environment that is at the specified _temperature. The extra resistance from this air film is why the full construction U-Value that you are getting out of THERM is a lower than just the (conductivity of material) / (depth of the material). Accounting for air films is particularly important when you get constructions that have a high overall conductivity (like a single pane window), since almost all of the resistance of such a construction is due to the air films.
To elaborate further, you might have noticed that, in the example files on hydra, I set this filmCoefficient to be either "indoor" or "outdoor", which basically uses some code that I wrote to autocalculate the film coefficient for you. I take into account both the emissivity of the material at the boundary (which gives you more air film resistance for lower emissivities) as well as the orientation of the boundary in the 3D space of the Rhino model. The code I wrote will take these parameters and match them to those published in ASHRAE Fundementals, which you can see in table 1 of the first page of this PDF:
http://edge.rit.edu/content/C09008/public/2009%20ASHRAE%20Handbook
I interpolate between these values in the event that your emissivity is not 0.05, 0.2, 0.9 or the orientation of your boundary is not any one of the 5 that they give.
I know that THERM also has the capability to actually run the radiative and convective formulas that you posted, Mauricio, as opposed to just using a single film coefficient to account for all of this resistance. The running of these formulas is particularly useful is the radiant temperature at the boundary is different than the air temperature. However, as long as you are ok with this assumption that the air and radiant temperatures are the same (which is the case for all of the situations that I have encountered), the film coefficient is perfectly sufficient. If anyone ever has need for this capability of running boundary conditions that have different radiant and air temperatures, please post here and I can think of a way to implement it. I rather like the simplicity of the current interface, though, and I think that I will keep it this way until we understand the purposes for why someone would need separate radiant and air temperatures.

he Summer in the City program, part of the Portland School of Architecture and Allied Arts (an extension to University of Oregon).
Using both Grasshopper and the Firefly plug-in, this workshop will focus on the design of innovative facade prototypes that are configurable, sensate, and active. Students will become familiar with the terminology used in interactive facade design including an overview of hardware (ie.sensors, actuators, and programmable microcontrollers) as well as software interfaces terminology. We'll learn new prototyping techniques and develop digital and physical models which can respond to a plurality of environmental and user driven forces. This workshop will take a hands-on approach, and you will walk away with the ability to build your own custom electronic circuits (using the Arduino), as well as create interactive simulations and models.
This course will primarily focus on physical computing techniques. Unfortunately, given the time constraints of the workshop, I will not be able to provide an extensive overview of the Grasshopper interface (it is suggested that participants have some familiarity with the Rhino/Grasshopper environment). There are many great online resources to get you up to speed relatively quickly if you are new to this software. This is a good place to start.
The course will be held at the School of Architecture and Allied Arts in Portland, OR. The date/times of the workshop are as follows:
Friday July 19, 5:00-7:50 P.M.
Saturday July 20, 9:00 A.M.-3:50 P.M.
Sunday July 21, 1:00-3:50 P.M.
If you are a designer, architect, or anyone who is interested in learning about the digital tools and technology trends that are revolutionizing design today, this workshop is for you. Make sure to click here to find out more about registration and enrollment in this exciting new workshop.…

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
