PenaltyInterfaceDiffusion
Overview
PenaltyInterfaceDiffusion is an interface condition that forces the variable equivalence using a penalty. At the same time, the flux equivalence is implicitly satisfied as long as no other side (interface) residual objects are present. Mathematically, it is written as follows: where and are material properties for the current element and its neighbor, respectively, and are the outward normal vectors from the element and its neighbor (typically . is the penalty supplied in the parameter "penalty".
