how to specify heat flux (convection coeff) on a wall boundary patch
 

Dear OpenFOAMers,

In OpenFOAM-2.3.x, there is a boundary type, externalWallHeatFluxTemperature the one can specify either heat flux or convection coefficient on a wall boundary patch. But, I cannot find one or similar in OpenFOAM-4.x. Can someone shed some light on how to specify wall heat flux/convection coeff on OF-4.x?

Thanks!

never mind! I found it.

Hi can you tell me how i can put a heat flux in a wall?

i have a pipe full of air, and i want to give heat flux as Bc.
