Hi, I am doing a Blow Moulding simulation in Polyflow in ANSYS Workbench 2021 R2. However, no matter what geometry I use and how I import it (.ipt, .stp, etc), I alway get a window with the following warning upon entering setup: “Unable to create skeleton of the mesh At least 2 boundaries per sub-domain are needed !” I can close the window and do the setup, but I can’t see the results afterwards, so I really think I need to solve this warning to be able to see the results. Any suggestions on how to overcome this error? Best regards, Hugo Silva, CiTin, Portugal
