How to update supply temp on one patch based on the measure temp on another patch?

er_ijaz · July 3, 2020, 09:48

I have a question regarding swak4foam or New expressions syntax. I need to measure Temperature (T1)at one patch and update T2=(Q/mcp)+T1 on another patch. I need to update at every iteration/time step is it feasible to do it via swak4foam or expression syntax?

There is a special coupled boundary condition that does this:

myPatch
{
type outletMappedUniformInletHeatAddition;
outletPatch aPatch;
Q 10; // Heat addition in W
phi phi;
value uniform 0;
}

More info here.
