Hello,
I have modeled a disc brake having two air zones surrounding it. The first zone is named "rotating fluid" as it will have rotating frame while the next enclosure has "fluid2" which will be stationary.


In cell zone conditions, I have given energy source for the solid.

All the zones are defined as rotating, but solid and fluid2 are given zero velocity (absolute).

In results velocity field seems to be good with results from other packages.

Issues:
1. It seems fluent is creating many walls, when I click on display them, it shows failed to create sliding interface.
2. The temperature in solid is reaching way beyond practical values.
3. The convergence graph is a straight line without any intent of getting low.
4. Have confusion about the coupled wall and the Matching options in "Mesh interfaces"

Thanks in advance.
