Hello,

I am having a doubt in rhoCentralFoam. I want to know where does psi get updated. As far as I know, psi gets modified when thermo.correct() is called. In createFields.H, thermo is defined as follows.

psiThermo& thermo = pThermo();

psiThermo inherits from fluidThermo which inherits from basicThermo. In both psiThermo and fluidThermo, correct is not defined. But even in basicThermo.H, the function correct is left undefined as the code below shows.

virtual void correct() = 0;

So I am not able to figure out at what other instances can psi be modified. Please help me in this regard.

Thanks, Vachan
