Hello All!

I am trying to make a very complicated mesh with cyclic bc on a couple of sides. I am getting following errors, the seriousness of which I do not understand as the meshing does take place eventually. Attached below is the error. Please let me know what do these errors mean so that I can make necessary modifications.

Thanks for your time.

Perhaps your faces do not match? The obj files written contain the current match.
Continuing with incorrect face ordering from now on!

Hello Nikunj,

I had a similar error message using stitchMesh and that way found this thread.

Did you scale any part of your mesh ? That might cause this problem.
Try to scale at the very end of the process, hope that helps...

I get a similar error, see here:

snappyHexMesh and cyclic boundaries

Did you guys figure out, what the problem was?

Best regards
