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.

Regards,
Nikunj.

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...

Did you guys figure out, what the problem was?
