Unable to perform 2D heat transfer

Hello everyone!!

I’m performing 2D simulation for heat transfer analysis between bed material (at 300 K) and hot air (at 1173 K). No flux (adiabatic) is considered for the walls.

However, I could not find the bubble growth pattern during the course of the simulation run. Could you please tell me where I’m going wrong? The bug report is also attached.
Thank you in advance.

Are you well above minimum fluidization velocity at the bottom inlet?

Thank you for the response Jeff. I have already adjusted the gas velocity considering the variation of density with temperature. Now the simulation result looks fine.
