fvDOM validation with analytical results
 

Dear all,
I am trying to reproduce the work of Amouzandeh et al. He uses analytical results to benchmark both P1 and fvDOM. I am in doubt of how to set up the fvDOM case for infinite parallel black walls separated by a gray media. I have a square domain of 1x1x0.1 with a discretization of 40x40x1. For the frontaAndBack faces I have an empty boundary condition. For top and bottom I have a symmetry plane and as reported on the paper, I am using greyDiffusiveRadiation for the IDefault file as follows:


dimensions [1 0 -3 0 0 0 0];

internalField uniform 0;

boundaryField
{

top
{
type symmetryPlane;
}

bottom
{
type symmetryPlane;
}

right
{
type greyDiffusiveRadiation;
value uniform 400;
}

left
{
type greyDiffusiveRadiation;
value uniform 600;
}

frontAndBack
{
type empty;
}
}

The problem is that my temperature calculated by buoyantSimpleFoam is converging to zero.

Does anybody knows how should I set this up?
For the P1 case all I had to do was to set G as:

dimensions [1 0 -3 0 0 0 0];

internalField uniform 0;

boundaryField
{
top
{
type symmetryPlane;
}

bottom
{
type symmetryPlane;
}

right
{
type MarshakRadiationFixedTemperature;
Trad uniform 400; // radiation temperature field
value uniform 0; // place holder
}

left
{
type MarshakRadiationFixedTemperature;
Trad uniform 600; // radiation temperature field
value uniform 0; // place holder
}

frontAndBack
{
type empty;
}
}

I am felling that I am losing something important
Thank you very much!
All the best,

Hallo Murilo,


please find attached the case set-ups of the mentioned "validation" cases.
