Meshing problems

Perchatuporn

To all

Since I am very new to star-cd, please forgive me if anything i post has already been solved.

The problem I am facing is that when volume mesh is generated, the error is found during assembling mesh, which shows

"Cannot find ngeom file:- TMP6_S~1\procadmesh.ngeom. Dualising mesh has failed."

After further looking in log file, the message in detail as follows is found

"cannot find closest point for vertex 2012252 on interface (eps=3.2614e-004)

vertex cannot be extruded! Cannot find ngeom file:- TMP6_S~1\procadmesh.ngeom. Dualising mesh has failed."

However if i change to mesh by other configurations, it seems to be ok while meshing. But the solver did not convergence properly and results become unrealistic.

It would be very kind of you if you can provide any useful information.
