Radiation source term
 

Hi,

I have to define a source term generated from a fixed point from fluid domain. My aim is to calculate the radiative heat transfer occurring between this source and surfaces ( turbine blades).

I read some threads regarding defining volumetric source term either by constant or UDF, but I could not come across how to define a point source..

I tried creating a new point inside of my domain and apply the boundary condition from there, however BC panel does not regard this point as a boundary.

Any help would highly be appreciated.

Davut.
