Please, does anybody have a comment on my last post?

Diego,

The pressure gradient term in the momentum equation for the "bouyant" solvers is based on a "dynamic pressure", which is defined/calulated as pd = p - rho*gh - pRef.
(see the file "createFields.H")

Mabinty,

The current distribution of OpenFOAM does not have a specific solver that combines all the capabilities you describe, though building a solver with OpenFOAM to accomplish this is certainly possible. Xoodles could be a starting point for this task.

Thanks Dave!!

The information that Xoodles does not have the capabilities I (probably) would need but though is a good beginning, gives me a good start.

Now I have already played a bit with Xoodles, solving a combustion in a simple 2D geometry. But till now I was not able to figure out what the solver is exactly doing or solving. Does it include radiation? Does it consider burning conditions (e.g. air-O2) influencing the evolution of the fire (complete/uncomplete combustion)? I keep trying out Xoodles to investigate my open questions; but of course I appreciate (and need) every information and hint!

Thanx in advance,
Mabinty
