Visualization False-color

Hi All, 

I am trying to run a section visualization in diva/grasshopper and study contrast ratio for a gymnasium wall. This is a south facing wall with a continuous band of glazing with 60% vlt. But every time i render it and see it under false color the glazing looks purple whereas it should be yellow cause it receives so much direct sunlight. 

Does anyone know why this is happening. …

Single node / calculation point

Hello everyone,

I'm quite new to Diva and I am trying to find whether you can insert one single calculation point (node) rather than a grid of points. I haven't found this option yet and I'm not sure if it exists. The alternative I've considered so far is to insert a very small analysis surface and set the spacing between points to the maximum available to get the fewest points in it (ideally one if I get the spacing right).

Any views or comments on this would be really…

Problem with Daylight Autonomy Simulation

hello, I am using Diva 4.0 (trial Version ) and rhino 5.0.I wanted to get climate base daylight autonomy result. I have added location assigned materials and placed nodes(around 59000 nodes).But when i am running my simulation it takes hours of times and then simulation does not show any result and gives these warnings. Please give me suggestions how can I solve this problem.…

Problems with installation: projectinfo

Rhino is in the same language of DIVA.

The problem is there even when I use the program like administrator.

Under I attacked the screenshots of response:

Mr.Comfy 0.16 released- spatially map E+ simulation results alongside DIVA metrics

Dear DIVA community,

during these past few years intensively working with & teaching DIVA, I have frequently observed the power of spatially representing daylight metrics to enhance the performance knowledge of designers and building science professionals alike.

Based on those experiences, I've authored a tool that extends the data domain of spatial metrics mapping to include the output of multi-zone thermal building simulations. It's available to you at…
