@beidongW Is this other post relevant? As in you are adding the additional component flow / scalar species advection to this free flow problem? |

I am implementing single-phase multi-component gas flow and found that my .i file fails to converge if I do not set boundary conditions. Components only stop accumulating at the outlet when I apply DirichletBC to fix the mass fractions. I would like to request assistance with three questions regarding my input file:
1、How should I set the boundary conditions to achieve free flow?
2、Is my kernel usage correct?
3、I have implemented a custom startup pressure gradient kernel that public PorousFlowFullySaturatedDarcyBase named StartFlowPressureDarcyFlow. Can this be used here? I still do not fully understand the relationship between PorousFlowAdvectiveFlux and Darcy flow.
