Hi Rob,

Thanks for responding!

I'm trying to simulate it for a steady state. I don't patch the volume fraction of the solid phase; instead, the components in the solid phase are given as sources in the packed bed zone.

Our institute has licensed Ansys, so it won't be a problem to access Ansys help. Can you suggest to me the links that I can refer to in the Learning Hub? I already contacted the customer portal but was unsuccessful in solving the problem. 

Kindly share if you know of anything that would help me in solving the problem. I can also share my case and data file if you require.

Thank again!
