How do I set Level 0 cell size in Hex-dominant (only for CFD) meshing nowadays? OR where did Base Mesh Box Discretization go to ❓

Hi Dale,

we have a feature request for that in our product backlog where I can link your request. Let me add some insights though:

  • The hex-dominant mesher did also not all allow to modify the basemesh resolution in the past. It was intended to be an easy to use tool specifically for unexperienced users, hence the level of automation of refinements etc.
  • The idea was always to improve/extend this algorithm to in the end make the parametric version of the mesher obsolete and let the user decide on the level of details that he wants to provide, essentially working his way down from full automation to more advanced properties. The first features on this roadmap would be the basemesh resolution as you mentioned and an opt-out of the automatic thin gap refinements that we apply.
  • Currently we are focusing our main efforts in meshing onto the new mesh preview, which will become our standard mesher, which leads to these improvements being a bit pushed back
  • The parametric mesher can also create internal meshes, you just need to put the point inside of the region of interest. We detect automatically in which region the point is placed and map the entities of CAD and mesh, so it should be even possible to use the CAD-based simulation setup in that case.

As you mentioned that the parametric mesher doesn’t help in your case, could you explain that a bit more or share your project. Maybe I misunderstood sth.

Best Alex
