Hello Everybody,

I am trying to set up a case for buoyantSimpleFoam - Solver.
But it forces me to specify a variable called p_rgh.

What is p_rgh? I cannot find any information, how to specify this variable.

Any Help appreciated!


Thanks Camoesas

Hi,

p_rgh = p - rho*gh .... you can find its definition in createFields.H file.

Bests,

HI,

thanks for the definition. But this doesnt help me to understand whats p_rgh good for. How can I calculate my initial values? Where can I find which boundary conditions do I have to set?
