Creo Simulate has tree default connectivities between component. You may choose between Free, Bonded and Contact for default rule for all interfaces and then define those which defer using Interface functionality. When models get larger it´s sometimes a challenge to remember classify all of them. Therefore, one might want to have a check of connectivity between components using Review Geometry functionality which can be found at Refine Model tab.
