Rotation in comsol

I have a query reading thermal simulation in comsol. I want to incorporate rotational motion into thermal simulation and analyze its effect.
I was able to run the thermal simulation, however when I tried to incorporate rotational motion by using Heat transfer in solids and then the transnational motion I got an error saying
Failed to find a solution, very ill defined preconditioner.
Can you please let me know the reason for it. I have attached my model if it is needed.
