boundary condition P1/MarshakRadiation
 
hello everbody,

I have a question concerning radiation simulations. I want to simulate Sandia Flame D with radiation. around the flame there should be no cover. so it is an open space i.e. openWall. should i use zeroGradient or MarshakRadiation for this?

openWall
{
type zeroGradient;
}
or

openWall
{
type MarshakRadiation;
T T;
emissivity 0; (= no emissivity)
value uniform 0;
}

what must I use at streaming in- and outlets? I'm asking because in the bouyantSimpleRadiationFoam/hotRadiationRoom case there are only walls and neither open patches nor in/outlets...

Thanks in advance

Marc

here you can see the G-file if this helps
and wall should be the "open" wall
