Momentum transfer term associated with mass transfer

Hi,

Can someone familiar with MFIX-DEM code tell me where the momentum transfer term associated with mass transfer between gas and solid phase is calculated? It took me lots of time to search it in the source code, but it finally failed. Can you please help me find it? Thank you.

Continuing the discussion from Code Structure of CFD-DEM in MFiX:

I haven’t given up searching this term in the source code these days, but there is still no result. I begin to doubt that there might be no such term coded in MFIX.
