Boundary conditions for PIC simulation

Hello,

I have managed to get rid of the need of CG_MI by rotating the problem and doing some bricolage on the BCs. However, I am still wondering how to apply a mass inflow in the inclined part of the reactor.

Also, do you have any recommendation for code analysis and dependency trees? I normally do it manually, but I am going to do some modifications in the code. For example, following the following thread to replicate the riser, and I want to make sure I understand everything I am doing. How to count the number of parcels in the solid outlet, and then inject the same number of parcels to the solid inlet in MFIX-PIC? - MFiX - NETL Flow Science Software Support (doe.gov)

Thank you!
