In rhoPimpleFoam, rhoSimpleFoam, buoyantPimpleFoam and buoyantSimpleFoam the density prediction step at the start of pEqn.H is now consistent between these solvers and the other compressible solvers. If the density is relaxed in the corrector it is now also relaxed following the predictor which improves consistency, stability and convergence.
