I have created a mesh by using CFD tetra mesh option in Hypermesh.I want the following quality index for the 3d mesh.

1.Aspect ratio <5

2.tetcollapse<1

3.skew<60

4.Max equi skewness <60

When I check Aspect ratio for 3d mesh, it shows the total boundary layer mesh as failed elements.What should I do to get rid of this problem?

If elements failed with given quality criteria, How can I repair those elements (CFD tetramesh).

If you are going to use AcuSolve, most of the cases do not need such a carefully generated meshes.

For Aspect ratios, you would have to generally change first BL height. Others are pretty much model dependent and difficult to say without looking at the model.

For CFD Mesh, I don't think you need check "aspect ratio" for boundary layer.

I created CFD tetra mesh with boundary layer mesh option.When I check the quality of tetra mesh, it shows total boundary layer mesh as a failed mesh.

If you don't mind could you tell, how can I create the volume mesh in Hypermesh for CFD problems?
