[ANSYS Meshing] How can I create Mesh for this geometry

ahmeterko · May 14, 2023, 09:34

Hello, I am trying to generate a mesh for Backward Facing Step geometry with flow control. I am trying to use coanda effect on BFS. There is a blowing at corner of the step.

In this geometry, what kind of mesh can I generate?

Thanks for help

Are you asking how to generate a mesh or which mesh? First, would lead to ansys meshing and second could lead to an unstructured mesh with inflation layers for example

Yes, I tried, but the mesh is not formed well enough.

Your first element height is bigger than the step in your geometry. You need to make it smaller
