I have a need to do a Boolean intersection of two unstructured multiblock datasets. It so happens in this case that the underlying element sets are polygonal meshes, so in this particular case I could also do what I want with a Boolean intersection of two polygonal meshes. To be (hopefully) redundant, I have two meshes which share some points and cells and each of which have other points and cells which are not shared. I would like a new mesh which consists of all the points and cells that are in both of these meshes. I need this to work properly in parallel.
I know enough to create a python-based filter (python programmable filter) to create this operation, but are there already existing Boolean mesh operations, and if not would those be a useful thing to add?
