simplify multiscale meshing #41

Closed krober10nd closed 2 years ago

Union of signed distance functions to define multiscale domain (no need for this UnionWithCovers concept).
Previous issue was associated with islands smaller than the minimum area threshold being removed in the main domain but not in the nests (or vice versa).

My thought on the image, is that is not that obvious where the inset and non inset mesh joins to see the contrast in mesh sizes across the domains. Can make it more obvious to see the contrast like the original figure?

krober10nd commented 2 years ago

The image has insets colored. Maybe you can try to make it then?

Thanks, yea agreed looks better. By the way could benefit from having a method to remove "small" connectivity in the mesh.
