Setting temperature boundary conditions for Convective heat transfer

huadian001 · January 12, 2017, 03:49

Hello Foamers,
I have got a problem with the temperature boundary condition settings.First of all, i use OpenFoam 4.0.1 and the solver is chtmultiRegionfoam.I operate according to the case from https://foamingtime2.wordpress.com/s...eneration/,but he uses third-party software swak4foam.Now it does not support the current version OpenFOAM 4.0.1.
So,Who can help me convert groovyBC format to OpenFOAM format.

convectionWater
{
type groovyBC;
value uniform 200;
valueExpression "Twater";
gradientExpression "0";
fractionExpression "1.0/(1.0 + k/(mag(delta())*hc))";
variables
(
"hc=50.0;"
"Twater=20.0;"
"k=0.5;"
);
}

swak4foam does work with OF4.0 if you manually apply a patch.
