A() and H() coefficients definition

And901 · September 30, 2014, 05:10

Hi everybody, i'm new to OpenFOAM and i'm trying to understand how pisoFOAM code works. I have understood almost all the code lines but i can't find where the coefficients A() and H() are defined or constructed into openFOAM.
I ask because i need to modify them.

Thanks for your help.

Regards,
Andrea

They are implemented in $FOAM_SRC/finiteVolume/fvMatrices/fvMatrix/fvMatrix.C.
Modifying these methods can cause unexpected results, because many parts of OpenFOAM depend on them.
