solve gas-solid two-phase flow problem by CFX-4.2
 

I encountered some difficulties when I was using CFX-4.2 to solve gas-solid two-phase flow problem. 1. The command file I changed from 'reference example 28' of 'examples manule' can not predict correct answer for gas-solid fluidized bed in steady state. Can some one hlep me and send me a copy of command file to calculate FB? 2. I can not calculate a gas-solid fluidized bed with a high speed counter-current gas jet located at the middle of the axis.

Thanks a lot!
