I am trying to mesh a 3D geometry in ICEM and create prism layers. I am using tetra unstructured mesh.

I first generate the mesh, and run mesh check. There are no errors. Next I run prism and get the following error:

------------------------------
prism: swap. C:616: base_vertex* check_collapse(base_vertex*,base_vertex*,unstruc_m esh*,check_collapse_opts*,merge_data*): Assertion e1->ptwin()->ptwin() = e1' failed.
Application is finished
Error: prism terminated prematurely.
-----------------------------------------

Does anybody have an idea what this error could mean?

Thanks!
