a surface(.STL file) cut the background region( a cube) to 2 parts. How to select one of the parts with setting parameters in snappyHexMeshDict?

If I want to compute the interior region of the bullet (assuming the bullet is empty inside), how to set parameters in snappyHexMeshDict?

Hello,

The snappyHexMeshDict parameter locationInMesh defines which part is selected for meshing.

Thank you very much

another question,

why the number of the refinement region is always 2? just by coincidence?

It is just a coincidence. You can have as many refinement regions as you want, or none.
