Energy equation in bouyant*Foam solvers
 

Hi all!

My question is regarding bouyantPisoFoam, bouyantSimpleFoam etc.

Would please someone explain, why energy equation is solved inbetween momentum predictor UEqn and pressure equation pEqn? Especially for transient solution we do not have corrected fluxes before solving pressure equation. So why should we use that "wrong" fluxes for energy equation in convection part???

Thank you for attention! Waiting for you replies!
