Wall BC for TFM simulation

Dear MFIX community, I am simulating a pseudo 2D GAS-SOLID fluidized bed using MFIX-TFM 19.3.0 GUI. I have noticed a discrepancy when setting the BCs for the gas and solid phases. Ideally I would like the gas phase to be ‘NSW’ and for the solid phase ‘PSW’. However when I set the NSW for the gas phase, the same BC is duplicated for the solid phase and vice-versa. How can I go about this? I have attached a MFX file for my case sscp.mfx (29.6 KB)
