Dear Friends,
I was wondering if it is possible to have a gradient boundary condition in the interface boundary at the same time with coupling boundary condition.

I aim to have a coupling boundary between solid and fluid and at the same time it should be a heat source in the interface boundary. I checked almost all related thread and also

http://www.cfd-online.com/Forums/ope...egionfoam.html

which is mostly to add heat source in the solver rather than on the boundary.

I was also thinking to have one side (fluid part) coupling:solidWallMixedTemperatureCoupling and the other side (solid part) fixedGradient: solidWallHeatFluxTemperature , but it didn't work.
I appreciate if you help me in this issue.

today i tried to test a case with chtMultiregionFoam.
my case includes natural convection in an enclosure with a block at the bottom. the bottom surface of block was heated.
the strange thing is that the temperature is not passing throgh solid zone to fluid zone. I am using turbulentTemperatureCoupledBaffleMixed as the boundary condition on the interface of soid and liquid zone.
I thinck there should be sth related to boundary condition. I will be too much thankful to recive you oponions .
