Dear All,
I have a problem with temperature in my simulation. in first step [0] it's ok 323K but in 1 step [1] it's 300K.. I use buoyantBoussinesqSimpleFoam with groovyBC My start files T Code:
dimensions [0 0 0 1 0 0 0];
internalField uniform 300;
boundaryField
{
RAK2
{
type groovyBC;
value uniform 323;
gradientExpression "gradT";
fractionExpression "0";
variables "heatFlux= 0.00005;gradT=heatFlux/kappaEff;";
}
RAK1
{
type groovyBC;
value uniform 323;
gradientExpression "gradT";
fractionExpression "0";
variables "heatFlux= 0.00005;gradT=heatFlux/kappaEff;";
}

 in 0 time step:  and then in 1 time step:  another problem is why in hot outlet "rak1in4" is stil cold air. it was defined as 323K..  any sugestion how i can do good symulation of this problem?  Thanks a lot, Sebastian |
