Hi!

I have a stupid, simple question.

The update of the U and p fields in icoFoam must depend on runTime.deltaT(). However, as far as I can see this timestep is only evaluated to calculate the courant number.

Where does deltaT affect the PISO algorithm? Maybe it is hidden in one of the #included pieces of code, but I can't find it.

Thank you
Nadine
