Guys, I'm a Novice, now a question stay in my mind. I built a simple model, and want to calculation force. When I choose form unions, it can get a force value. But, when choose form assembly, what it get is 0. Why? Is forming assembly the only choice in AC/DC modular? But I see some case choose form assembly. So did I make a mistake? Can somebody tell me?

If you have moving geometries, it helps to use form assembly. It creates separate objects, each with their own mesh. If they are in contact, you probably have an identity pair, or similar.

Check your solution in the case of the form assembly. Is it the same as form union?

But, if you have what you want using form union, why not just use it, and forget about form assembly?
