Hi,

I try to modify laplacianFoam solver and make depency of DT from temperature. Something like this:

if T>0 then DT=0.56 else DT=2.21.

Taking a temperature from previous time layer is ok. But i don't understand how to make OpenFoam fill each value of dimensionedScalar from respective value of calculated T.

some thing like this:

forAll (T, celli)
{
if (T[celli] > 0)
{
DT[celli] =0.56;
}
else
{
DT[celli] =2.21; 
}

}

P.S
you should change diffusivity definition from dimensionedScalar into VolScalarField
