Detecting negative vlomume elements in ICEM
 

Hi everybody

What Kind of quality type should be checked in ICEM for Unstrct Mesh to find the negative volume elements? I checked Quality, Determinant, Skew and Aspect Ratio in ICEM but nothing were found. However when I import the mesh into CFX I get the negative element error.

Hi Henry,

This has been discussed in topics before.
In the quality metrics graph, there's an option to display quality by volume. If you look at the histogram, you'll see that your minimum value will be zero or negative. Highlighting this bar will allow you to see where the negative volume elements; you can work from there.
