Bug with plugin crack when an additional physical surface is defined
Plugin crack seems to behave properly in the attached initial configuration (data_crack0_a.geo). The node of coordinates (-10, 565, 100) is duplicated and both nodes with the same coordinates are referenced by volumic elements (tetrahedra). If I define in the geo file an additionnal physical surface (data_crack0_b.geo), the node of coordinates (-10, 565, 100) is still duplicated but only one of both nodes having the same coordinates is now referenced by volumic elements. The other node is not referenced by any tetrahedron, it is only referenced by surfacic elements belonging to the added physical surface. bug_crack.7z
