Hello all,

I've used this solver for a run, but the results showed not very satisfactory. I'm trying to understand if it is out of setup problems or the algorithm of this solver.

Has someone experience (validation assessment) using it?

I've read the wiki documentation for BuoyantBoussinesqPisoFoam and here are some changes between Simple and Piso.

The following operations for UEqn:
fvm::div(phi,U)
-fvm::Sp(fvc::div(phi), U)
+turbulence->divDevReff(U)

What does the second operation do? Sp(...)

From math point of view, is it essentially the same as Piso except the transient term?

Best Regards,
walker
