Detailed Description

Buoyancy related data for the Foam::solvers::isothermalFluid solver module when solving buoyant cases with p_rgh and is selected based on the presence of the p_rgh field file.

Provides: g : gravitational acceleration hRef : optional reference height pRef : optional reference pressure ghRef : -mag(g)*hRef gh : (g & h) - ghRef ghf : (g & hf) - ghRef p_rgh : p - rho*gh - pRef

The Foam::solvers::buoyancy::New function returns an autoPtr<buoyancy> pointer containing either a buoyancy class pointer if the p_rgh field file is available otherwise a nullptr which can be checked using the autoPtr::valid() member function.
