[Thank you for help] For a heat transfer problem, how to add a conductive BC.?
 
Hi guys,

I've smoothly ran a simple heat transfer problem with fixed temperature value at BC.

Now, I need to change fixed BC temperature value to convective BC, like h(Tsurface- Tenviron) = - K (DT/Dn), where Tsurface is transient, and Tenviron is a fixed value

As a newbie to OpenFOAM, what should I begin with? Can anyone give me a clue? Or some code lines?

Thank you for help and instruction.

Hello,
have you tried to use what Bernhard Gschaider made for these cases
groovyBC, funkySetFields and swak4foam?
