Hello!

I had a look at the fixedFluxPressure boundary condition and I am not quite sure to well understand what this BC does.

I guess I have to use this BC if I want to evaluate the pressure according to a velocity input. Am I wrong ?

Furthermore, in the code source, one can read:

        gradient() = (phip - (patch().Sf() & Up))/patch().magSf()/rAp;

I do not succeed in linking this snippet with a mathematical formula...

All enlightments are welcome!
Regards,
Cyp
