How to add multicomponent equations to the steady incompressible solver?
 

Hello to all,

At present, I encounter difficulties, that is, I need to establish a steady-state multi-component incompressible buoyancy solver.
There are only two basic solvers related to it, one is buoyantBoussinesqSimpleFoam, and now it is only necessary to add multiple components to it, but my many attempts have failed, and there is no solution yet.
The other is rhoReactingBuoyantFoam, which needs to turn off the reaction switch, then change the transient state into the steady state and the compressible state into the incompressible state. In the process of modification, many problems were found that satisfactory results could not be achieved.
So what ideas or solutions do I ask you for help now?
Thank you all and wish all the best!
