I’ve been trying to run an urban wind simulation with Butterfly, using a complex terrain. I drew a wind tunnel manually in Rhino, with the sides trimmed to the terrain. I then input the surfaces as an indoor case, with inlet, outlet, sides, top and terrain. Unfortunately I seem to be having a problem meshing.
I noticed this topic had been brought up in the legacy forum here: http://www.grasshopper3d.com/group/ladybug/forum/topics/lb-terrain-generator?commentId=2985220%3AComment%3A1583933&groupId=2985220%3AGroup%3A658987
Has there been any development since then? It would be great to have an example of this type of workflow, so that it can be followed easily!
