Hello everyone: I have an old question, which has been mentioned many times in the earlier discussion. The problem is about the normal direction of an interior facet: Assume \Omega_1=[0,0]\times [1,1] and \Omega_2=[1,0]\times [2,1], thus x=1 is an interface with facet id=1. Then, if we would like …
