i am filling a mold which has 2 injection locations. When i look at the filling pattern of the molten polymer, it looks a bit strange (please see the attached pic). This is a snapshot at an intermediate time step. You can see that there are patches which are surrounded by molten polymer. I dont think this can happen in reality. Has anyone seen this kind of behavior or know why is it happening?
PS: the mold temp is uniform all throughout. there aren't any local cold spots. This is a solid mesh.
