Hello everyone,

I am writing my own solver, By using PISO algorithm.The Governing equations are given in below picture. I am modeling this as BuoyantBossineqPiso solver model. Because my density is changing during the simulation.

Actually, I have a Doubt that can we use fvc class in predictor step of Piso algorithm. because I have not found the use of fvc class in any solver following Piso algorithm. When I compile the solver it is showing up to date still, I have a Doubt that is it Correct or not? For clarification purpose, I am attaching my Solver.C file and Create field file also.

Please help me out of this Doubt.


Thanks in advance.
