2D model coupling

I want to couple two 2D models, the first models computes a stationary state and the second should use the result to compute a time dependent model. I thought that with identity mapping I could read the results from my stationary and use them as initial condition for the time dependent model.

I know that the problem in this case it can be solved easier, but I want to use the concept in a bigger reaction engineering model.

Thanks in advance,
