<p class="MsoNormal">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.<o:p></o:p></p>
