algorithmic modeling for Rhino


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.

Unable to have DIVA Plugin work within Grasshopper. 1 Reply

I have downloaded the most up to date DIVA Plugin for Grasshopper that is to be used within Rhino software. I have saved the DIVA plugin in all Grasshopper components folders. Upon opening Rhino, and…Continue

Hi, I'm new to Diva in grasshopper and now working on some simulations about illuminance. 

When I press button and run it, I saw the message saying, "Starting raytrace on 4 grids...

generating octree

octree complete

starting raytrace"  and didn't work.

What is happening in Diva?

Does anyone help me?

Is there a way to automate the annual glare analysis in Grasshopper?

Hello all,

I'm quite new at grasshopper and DIVA.

I am trying some irradiation simulations for my thesis on a simple geometry and I am getting some really strange results. The north oriented surface of the roof  is getting higher results than the south one (for city at north hemisphere). Can anyone guess the reason, or did anyone face this problem in the past? what do you think I should change?

Attached you may find the .gh file and the climate data file.

Thank you for your time.

@ Mohamed hegazy, Thanks in a million I will try that now (Y)

Try Flatten the ground before Connecting to shades

Hello every one, I've a little problem concerning Thermal simulation, when I add the surrounding context as a berp beside the facade elements as  a shade it runs the thermal simulation twice, giving me two results of everything. Any clue what might be the problem!!

Comment by Israa El-Maghraby on February 26, 2015 at 5:31am

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