Sorry to ask such a basic question, but how do you refine the mesh for a specific region (not an entire domain) in 3D.
I cannot get 'Mesh Control Domains' to work for me, but i think this would be ideal, where I could place a sphere and set everything within this sphere to be mesh controlled. However when I attempt this and put the sphere in the 'Domains to include' and click build, the active switch turns to off, and the sphere does not disappear, it remains as a solid object which gets meshed.
In 2D I can control the mesh as above using lines and mesh control boundaries as per the user guide p969. Also in 2d I can use 'size' with point or boundary, but this does not seem to work in 3d, or makes minimal difference. (though this solution would not be ideal anyway).
Thank you for any help offered.
