I set up a model, very simple cubic block and checked everything is ok. I wrote geometry/prob out with check. Everything is ok. Then I run the program. It stop and message say: negv found cell number 8158, probably left-handed cell. But I check the cell and it is not left handed. I even count the vertices of its eight corner! Can anyone give a clue?

1. Just a try- Delete that cell and create manually using its vertices. Sometimes it works. 2. Put that cell in cset and check its volume. Cheers....

Thank you John. I wrote out the mesh to a new file and the mesh works well. I tried switching the problematic cell into solid but then the cell next to the mentioned cell become negv cell once running. I switched again and then again the cell next to the previous one cause trouble...
