I want to calculate the flow in a space with square bulges on the ground( for some reasons I have to use Creat Case From Geometries). However, the result does not show the obstruction of the square bulges to the flow. I don’t know how to get it right, please help me out!
Can you share your grasshopper files?
If you want to create the box as a closed surface separate from the rest of the wall, try to create the bottom of the box slightly below the floor.
