[ANSYS Meshing] Sweep mesh with multiple bodies not always working

jlo1124 · May 19, 2021, 15:16

I am trying to sweep mesh the below geometry and it yields a totally failed mesh. I can create an independent sweep command for each body which works, however when I do it all in one it fails yet it has worked before in the past. For obvious reasons I refuse to sweep each body individually.

Somehow got just the tubes to mesh by trying the exact same thing over and over again. However half the tubes have a horrible mesh inside even though there are no bodies. How is this possible?

Are these separate parts or in a multibody part? Have you checked if Meshing sees that sees are sweepable bodies (RMB on Mesh in the tree)? Have you tried the Multizone method?

Yes, it shows they are all meshable geometries. For some reason it is always sweeping to some singular point far away from the part
