Problem solidification and rotations.
 

Hi, i´m having a little problem with fluent, and i don´t know if it has a solution.

I´m modelling a 2D Solidification problem.

i have two concentric circles the first is maden in iron-cast and it´s in rotation (this is the great problem). Inside of that circle i have a ring (one wall is the iron, the other one is adiabatic) with the fluid tin.

The materials are a diferent temperatures.

Everything works at the TIN arrival to solidification temperature (503K), then, always my simulation breaks.

I can to solve the same problem if the walls are quiets (with gravity on or off), but i can´t to able to solve with rotation.

Do can i make it???
