Hi
I am using solverIB for getting pressure drop and velocity distribution in a packed bed. I have found that the pressure drop and velocity magnitude keeps on increasing as i decrease the cfd timestep. The pressure drop varies from 250 Pa to 10000 Pa as i vary cfd timestep from 10^-4s to 10^-7s. The analytical pressure drop is around 400 Pa. I have adjusted coupling interval accordingly when i vary cfd timestep.
I have found similar queries in the forum but no solution yet. Can somebody help me?
Thanking You
