Non positive volume exist - How to find where ??!!
 
I am using STAR CCM+ for cfd simulation.After volume meshing,when I tried to initialize the solution, the software is showing an error message "the mesh may have non-positive volume cells. How can I correct this error using STAR CCM+ ?

You have two options. 1) Add or fix your mesh controls which are resulting in the degenerate cell(s) or 2) right-click the region and select 'remove invalid cells'.

I would highly suggest exploring option 1 first.
