I am a beginner of Diva. I would like to use Diva for grasshopper to achieve the parametric simulation and optimization in urban design. In my model, I have finished the daylight simulation just for one block. When I change the slide of basic grid to generate several blocks, the daylight output shows error. It shows that "Solution exception:Object reference not set to an instance of an object".
I would appreciate if anyone can correct my definition in the attach files. Thank you all!
This is the daylight analysis for just one block.
