Hello Everyone!

I tried to model a composite pressure vessel using Ansys ACP. The identical lay-up was applied for the side of the cylinder and the dome part at the junction. However, it seems that the thickness of some layers at the junction converges to 0 after I generated the solid model in ACP. I would appreciate it if you would answer the question.

Best regards

nThanks for being patient. This typically happens if you try and create the parts thinking they are separate and hence have an oriented selection set (OSS) for the cylinder and one for the dome. Instead, if you wish, you create a single OSS the includes the cylinder and the dome element faces, then the plies will not drop to zero. nA better way can be to leave as is, that is in separate OSSs, but when you create the modeling ply, be sure to include both OSSs as shown below (.1 and .2). Here I have 4 plies that will be continuous across the two OSSsnThere is one other reason you may get what you see and that is if your surfaces do not share topology and there are multiple edges where the surfaces meet. Here we use shared topology in SpaceClaim to share those edges. See if this fixes the issue. Thank younRegards,nSea

Hello Mr.sharvey,n I managed to fix the problem by using single OSS as you told me. Thanks for the answer!n Best regards
