Question1: My understanding is that a compatible mesh is one where the nodes of mating faces or edges of adjacent bodies are aligned. Please confirm this is correct.
Question2: My understanding is that bonding is never a problem where a compatible mesh exists. Please confirm this is correct.
Question 3: My understanding is bonding may or may not be a problem with an incompatible mesh. Please confirm this is correct.
Question 4: Please clarify the purpose of the 'remeshed failed parts with incompatible mesh' option. What does this do? I have found that a study will mesh and run without problem on occasions with this option unticked even though the mesh between adjacent faces is not compatible.
