Hey Everyone,

I am currently running the blockMesh-snappyHexMesh combo, but I need some help. I'm trying to get the mesh around my imported object to have a finer mesh. As of now, the gradient of mesh fineness quickly turns the mesh into rather large cells.

Is there a way to make the mesh generated around the object to expand to the entire blockmesh or at least a direction?

In snappyHexMesh, you can do some distance refinement from the .stl surface doing something like

  refinementRegions 
  { 
  
      sphere.stl 
      {                             // refinement level 5 within 1.0 m 
          mode distance;            // refinement level 3 within 2.0 m 
          levels ((1.0 5) (2.0 3)); // levels must be ordered nearest first 
      } 
  }

This is a per-stl surface and not a per-patch feature of SHM. See some of the documentation for further details.
