DIVA for Rhino

DIVA-for-Rhino is a plugin which runs thermal, daylight, solar radiation, and glare simulations. Our goal is to bring validated environmental simulations directly to the conceptual design environments of Rhino and Grasshopper.

Hello Jeff Niemasz Awesome Plugin, but I've a little problem that the thermal analysis takes longer time than it should. It always stops at Initializing simulation for about 20 minutes. There's any way to make take less time. the shading element consists of like 12 planar surfaces, so as mush as i guess no modeling problem. Let me add when I only test one planar surface it runs quicker

Thanks in advance

Hi everyone, I was wondering if Shaderade has been incorporated in the latest Diva versions?

I have found a similar question asked on November 2012 without a clear answer. Could you please inform me with anything related to the Shaderade component?

Adam -- 2.0.0.7 is correct.  I think Jeff got a little ahead of himself.  :)

Hi Jeff. I just reinstalled diva - version 2.1.1.1, but the grasshopper version is still being shown as 2.0.0.7, not 2.0.0.8.  Is 2.0.0.8 included as the DIVA.ForGrasshopper.gha in the C:\DIVA folder? I copied this into my gh components folder, but I'm still seeing 2.0.0.7 as the component version, not sure why..

Comment by Jeff Niemasz on March 10, 2014 at 7:24pm

Hi Adam,

This should have been corrected. If you right click on a component you will see the version- if it is not 2.0.0.8 then you should install the latest version. Let me know if that does not resolve the issue.

Thanks Jeff. I would like to use the GenericTranslucentPanel_20 material, but this material is not shown in the gh material component even though it is in the material.rad file and accessible in the rhino diva menu. Not sure why it is that I can't get to it in gh. I see in the material.rad file that "The model requires the following two files have been added to a directory included in your RAYPATH variable (c:\daysim\lib or C:\Radiance\lib): rang.cal & Translucent20.dat" I'm not sure if this could be the problem because I only see "rang" in my Daysim\lib and I don't see "Translucent20" in either folder.. Any thoughts on this? I found that someone else had similar problem not seeing the translucent material in the gh menu.. here.. Not sure if they resolved it..

thanks

Adam

Adam- instructions for creating a custom radiance material for the grasshopper component are here.

Comment by Adam Castelli on March 3, 2014 at 10:16pm

Hello. Is it possible to use a translucent glass material in a daylight analysis using Grasshopper? The specific problem I have is that I would like to model a translucent skylight and use grasshopper/diva to test angle variations of shading fins above this skylight on interior illumination levels. As there is no translucent material in the gh diva material component, is it possible to assign a custom material in rhino and then include it in the model which is analyzed when the gh daylight analysis is run? or another way to do it?

thanks

Adam

The component is crudely meshing a nurb surface. Try meshing the curved surface to the desired resolution and then pass the mesh to the component.

Comment by Germán Gonzalez Damonte on February 12, 2014 at 6:15am

Hi,

I have a problem with the geometry. It comes as a curved wall to the input on the Diva material component and exits as a simplified straight wall after this component.

Any advise or help?

Cheers!
