Hi foamers,

I specified a fixedGradient boundary condition for the temperature in a patch at the wall.
How can I access this value from inside the solver to do some further calculations?

Any help appreciated !

Cheers,

Pascal

I figured it out by myself. I wanted to access the temperature gradient at the wall.
It's actually pretty easy. I somebody is interested to code is as follows:

scalarField gradTField = T.boundaryField()[heatedWallPatchID].snGrad();

Hi,

What should I do if I want to access temperature value at inlet in fvPatchFields to modify boundary condition.
