Ah, OK. If you provide a marker for one of the external boundaries of your mesh, you need to do so for all of them. You currently have: Physical Line(3) = {1}; If you also set physical lines for the geometric lines 2 through 4 in a similar manner, then things should work. Or, if you don't need to apply boundary conditions to any of the walls individually (and therefore don't need to distinguish between them), then you can delete that one Physical Line. Lawrence I
