Hi all,
I'd like to run a few simulations in fireFoam where the density is fixed and doesn't change. One solution I know to this would be to change the fireFoam solver itself to prevent it solving for density. However, it makes it much easier to run these simulations on university computers if I can do it with the standard solver. Is there some way to change the thermodynamic properties or choice of thermo model such that the density is fixed? I intend to determine to what extent the flame is determined by my velocity boundary conditions and to what extent it is driven by the buoyancy of the heated air.
