Negative elements
 
I'm tired trying to solve this problem... ICEM 10 CFD. I can't see any problems in mesh, but CFX tells that there is a negative element volume. Tried Blocking->Block checks->fix inverted block. Tried to fix mesh, but more I fix, more problems to fix appear. Is there any way to look at this negative volume element??? There is nothing special in my project pre-mesh looks valid

Re: Negative elements
 
What are pre-mesh quality parameters you have checked? There are two ways to identify negative volume. In Pre Quality Check, you can show negative value of either "Determinant 3*3*3" or "Volume".
