Hi guys .
I have a problem when I tried to use butterfly to simulata a urban size model .
I found some similar issues in both iscourse and github , and the possible solvations I know now are two following operations:
1.Refind and smooththe mesh for the reason that it requires a high quality mesh to calculate .
2. Offset the calculation surface , because some probes may cosidered as inside the building .
I tried both , however , I still got unusal values as you can see in the illustrate.
The mesh I created :
The test point I created :
I really need you help ,I have tried several way but it just doesn’t work .
Please tell me if you have any possible solvations or ideas ! ! Thanks ! !
