Errors in Gambit for boundary layer mesh

Mike Spears

hi, Everyone

I am facing the following situation: I added the boundary layer to the surface of a foil, it looked well for this boundary layer. Then I wanted to put unstructured grid around the foil, strange thing happens, the boundary layer close to the end of the foil was modified, there are yellow lines inside the white lines for the boundary layer region. The final grid had negtive cell area at this region. Anybody also have this situation and have suggestion to fix this? Also another question, when FLUENT read this grid, it reports an additional zone name shell conduction zone, what does this zone mean?

Thanks a lot
