Solving Time dependent problem with stationary solver at the same time.

Hi,

I am trying to simulate a brushless DC motor. I want to make comsol to solve the problem in the form of time dependent. However, during each time step, comsol should solve and obtain a stationary solution. This mean that the main solver is time dependent and stationary solver in each time step. How can I do that?
File is attached.

Thank you.
