Why aren interblock connections set correctly after importing a grid from a PLOT3D file?
Gridgen is unable to automatically match some interfaces where a single block face matches up with multiple other block faces. In these instances the user will end up with overlapping or coincident domains at these interfaces. You must split the larger domains to match the smaller ones. Once splitting is complete, Gridgen will recognize automatically that there are now duplicate coincident domains, remove one of each pair, and set up the interface properly.
