Dear all!
I am currently working on the simulation of the external aerodynamics of a car with a little bit of underhood regions and I am using the CutCell method in Fluent Meshing mode (18.1).
My problem is that the mesh check fails due to some left handed faces even without morphed prism layers. When I add prism layer more left handed faces occur.
For testing purpose I even neglected the underhood part to simplify the geometry. I also visualized the left handed faces and removed the areas in the model. After remeshing left handed faces appear somewhere else in the mesh.
The CAD input files are .stl.
I wrap them to get a surface mesh.
I check and modify the surface mesh to get 0 free, multi and duplicate faces and a maximum skewness of <0.7.

I really worked through all information and tutorials I could get about CutCell meshing.
Unfortunately I couldnít find any information about left handed faces with CutCell in the Ansys Manual, the internet and this forum.
Commands like mesh/repair-face-handedness in Fluent Meshing mode and repair in Fluent Solution mode donít seem to work.

Is there anybody having the same problems and solved them?
Is there maybe a vital check I didnít do with the surface mesh?
Are there commands to prevent the formation of left handed faces prior to meshing or post meshing?

Generally I want (have) to stick with the possibilities of Ansys 18.1.
Furthermore I also want to stick with the CutCell method due to turnaround time and mesh size.

Thanks in advance!

Sorry I can't help but I wanted to comment so I can follow this thread in case someone has a solution...I'm also having an issue with checking the cutcell mesh in fluent (although mine says that there is an element with only faces)
