inflation layer problem

      Hello 


      How can I fix this unstructured inflation layer which takes place on both ends of this water pipe? The pipe length is 200m and as you can see in the photos the inflation layer is really unbalanced at the edges (for a few meters) then smooths itself out.


      Thanks in advance

      That looks like you've got two volumes, so two inflation layers. Re the odd inflation to the right end, what's there? What settings did you use?

      Yes there are two volumes with shared topology. The bottom is fine, but the top has the weird behavior on the two sides. 


      These are the inflation layer settings, pretty much it's basic.

      Anyone?

      Most staff don't come on here over the weekend.


      How was the geometry generated. Inflation shouldn't do that, but slight distortions in the edge could.

      Oh ok no worries Through spaceclaim. Is there any way to attach the geometry and mesh file?


      Thanks

      Yes, but as staff I can't do anything with it! We're not allowed to download files.

      No worries. The geometry is pretty simple, don't know why this anomaly in the inflation layer occurred. Any more suggestions to solve the problem?

      I also get the same problem. Did you have the solution for that inflation ?n

      Part of the problem is having two volumes: no idea why that is the case so can't comment. If you add an image of your mesh we can review that. n
