Volume fraction distribution does not seem right in TFM 2D case

Hi Mfix community

I’ve been trying to simulate a TFM case with a geometry similar to the Silane Tutorial, but just the fluidization process so far. It runs, I can see the outputs and it seems alright. However, when I visualize the volume fraction distribution it does not seem to be right it is like only the bed interface changes and I can’t see the gas entering from the inlet BC. Does anyone know what might be happening? The mfx file is attached below.

Make sure your inlet velocity is above minimum fluidization.

Thank you. There were some wrong parameters so the inlet velocity was below umf.
