If two blocks overlap, are they considered continuous and a union?

Hi,
I have two blocks that both have the same dimension that i want to sweep. The two blocks overlap. Are they considered a union during simulation?
Thanks.

Hi
if in the geometry section you have two objects (volume sin 3D, surfaces in 2D) that overlap, and you use Finish union mode, these will be united into 3 entities (domains in this case), with common continuity type boundaries
If you use Finish assembly mode, you will end up with 2 entities that overlap (which might not be physically correct, all depends what you are after), and your physics have no default continuity boundary conditions. Yo umust defien your pairs yourself and define the physics linking them manually

Good luck
