hi
I'm a beginner.I want to model dropping a rigid body into water by cfx.
anyone can help me?

Is this post a duplicate of this: http://www.cfd-online.com/Forums/cfx...-velocity.html

If so then I will delete this thread and all discussion should occur on the other thread.

I dont think so,casue in this topic the rigid body falls because of gravity but in another topic,it has a constant valus

So in this case you probably need a rigid body model but the other one is just a moving mesh simulation. So yes, you would model them quite differently.

But I hope you are not expecting a step by step guide on how to model it - that is not possible on an on-line forum. If you have a specific question we will try to answer it.
