Dear all

I am a newbie of cfx's users that would like to simulate the behavior of fluid inside the rotary drum attached with baffles. First of all, I create the geometry like a rotary drum attached with baffles and then define the baffle as the internal wall. After that, I write the input for cfx pre program.

In the cfx pre program, I specify the wall and baffle of rotary drum as the rotating wall but I found the problem which is the terminate run in the cfx solver. So I need to change boundary condition from the above condition to specify the wall of rotary drum as the rotating wall and baffles as stationary wall. Then I run the simulation and get result.

In the result of cfx post program, the result is the wall rotated but baffles is stationary.

So, I don't know how to define boundary condition for the baffles and wall are rotating along the z-axis

Pls help me.

Thanks you for your suggestion

Best Regard
