zwldlut is on a distinguished road
Hello everyone,
I'am simulating a fluidized bed dryer for drying the particles. Primary phase contains air and water-vapor,secondary phase contains solid and liquid-water.
Time step is 5e-5.At the beginning, it rans well. But after 90000 iterations, the solution is not converging and shows the error of Error: Divergence detected in AMG solver: gas-phase-species-0

I have tried to reduce the relaxation factors but it is no use.

I will really appreciate to some suggestions or help from forum friends.
Thanks in advance.
