While trying to clean-up and mesh a geometry, follwoing messages repeatedly appeared: (1) ERROR: SIGSEGV (Segmentation violation) while meshing v_face.33 (2)TGlig received signal SIGFPE (arithmetic exception) error: Traingle surface mesh of face v_face.33 failed (3) Cannot operate on face v_face.55 with associated real geometry (even though the validity check result says "0 out of 18 faces failed teh validity check)

Any information of these error message which will guide me to complete the meshing would be highly appreaciated.

Thanks a lot in advance, Amod
