yasushiueharaparkcitynejp is on a distinguished road
I want to ask how to construct a solver of a radiative heat transfer problem and how to give the boundary condition.

The abstruct of calculation is as follows:
The radiation from the sun (or a black body) is heating a pipe. (An intensity and a direction of the radiation are fixed.)
Then water flowing in this pipe is cooling the pipe.

Under these conditions, I want to calculate a distribution of temperature of water and the pipe. If it is possible, I also want to calculate a distribution of temperature of the air around the pipe.

I searched a buoyantSimpleRadiationFoam and a chtMultiRegionFoam. I think I need functions of the both of these two solvers.

Have I got to construct new solver?
If I do not have to construct new solver, which solver must I choose?
