Hello all,

I'm new to snappyHexMesh. I need to increase the mesh density in a specific region to do a flow simulation. So I'm trying to keep both inside and outside of the STL. However locationInMesh will only keep one region and remove other cells. And if I delete that snappyHexMesh won't run. Anyone knows how to keep all of the cells in the bounding box?

Thanks.

Mesh it twice and merge the meshes? But really it sounds like what you really want is just a high resolution section - is the geometry of this section too complex for searchable spheres/boxes/etc?
