Concept of conformal and non-conformal interface
 
Hi

Could you tell me what's the concept of conformal and non-conformal interface? I tried to search for it online, but I didn't find any good answer. Thanks!

Both are interfaces and there is averaging of data on both sides before transferring to other side.

Conformal interface : An interface with equal no of nodes on both sides.

Non Conformal interface : An interface which does not have equal no of nodes on both sides

Just a minor correction here:

A conformal interface is not defined by an equal number of nodes on both sides.
Instead, the meshes on both sides of the interface have to be conformal:D, which means that every node on one side of the interface can be matched with a node on the other side of the interface with a very low tolerance.
The advantage is that there is no (additional) interpolation necessary at a conformal interface. This makes the computation faster and more accurate.

Consequently, a non-conformal interface can be set at two faces with the same number of nodes.
