Radiative boundary conditions

diegon · December 14, 2006, 14:09

Hi everybody,

I am working on radiative transfer equation solving by the simplified spherical harmonics method (SP_1).

I would like to know if the snGrad operator can update the value of the gradient value on a boundary if this is set as a fixedGradient.

Thanks in advance

Diego

Hi Diego,

if you search for the conjugateFoam solver in the discussion and you give a look on it, there is a way of updating the fixed gradient boundary condition..

Hope it can help,

Daniele

Thank you very much Daniele, it works.

Dear Diego,

I am also interested in radiation and wall heat transfer, when you are done it would be nice if you can upload your solver..

think about that =)

Hi Diego,

I would like to use OpenFoam for radiation too. It would be nice, if you upload your solver... :-)

Maybe, someone else did some coding step into radiation problems!?

Regards!
Fabian
