I had a solver problem concern to grid interface between stationary and rotating components.

I am trying to analyse the flow some part of coal pulveriser comprises inlet duct, bowl and vane wheel.

Here the domain of vane wheel is rotating and rest is stationary.

When used forzen - rotor interface at this junction and runned, solver shows fatal errors.

Can some body helps to correct this problem. More details will be provided after hearing from the users.

What are the fatal errors?

Is your initial guess fairly reasonable?

Is it failing during a solution or startup?

Some of these questions should help people answer your problems. If not, CFX has awesome support.
