When creating a Mesh, one can choose “Hex Dominant (CFD Only)” which has much less inputs than the Parametric version. However, it seems as though you can add a few refinements but the help bubbles are a bit confusing. For example, for “Inflate Boundary Layer” under the “First Layer Thickness”, it isn’t clear what the units are. Plus, the help bubble talks about the “Final Layer Thickness”. So which is it?
Second, under “Surface Refinement” it shows units of “m” for the “Length field”. Is this really in meters or is it relative to the mesh size? The help bubbles talk about levels and not length. I though all refinement “Levels” where actually relative to the base mesh.
Third, under “Region Refinement” using internal, there is a “Length” field with units of “m”. I am familiar with the “Region Refinement” using parametric where the value is a “Level” but this is kind of confusing and there is no help bubble for that.
