#1) Is there a general convention of which body to make the i or j body in contact for best performance? i.e. the larger body should be i, smaller should be j.
#2) Regarding complex geometry, I noticed that it is suggested to split apart geometry to the region of contact. Does this mean that, say I have contact in an inner diameter of a larger part, that I should make the region around the contact area a separate part? i.e. make the single, larger part into two separate parts (connect with a fixed joint)? My understanding is that this is easier on the solver trying to locate points of contact
