Modeling of Rotating Porous media

Respected Members,
I am trying to model the flow in a Rotary heat Exchanger in 3D and for that I am assuming flow through a Porous media.
I tried rotating the porous media domain via the independant interface provided in Comsol 5.3a. I have applied the "Flow Continuity" only on the Face boundaries of the porous domain (as indicated in the attached model). Also, I have used Wall Condition: Leaking wall under Flow contnuity to make sure flow passes through. But, I am not sure if this correct.
Also, since my simulation is time dependant, I tried running the model for 2.5 secs (Random choice), But I get below error - "Nonlinear solver did not converge. Maximum number of segregated iterations reached. Time : 1.9600581668633166 Last time step is not converged."
Kindly, help me in understanding to where I am going wrong and what I can do correct my model.
Attached is the model.
