solar modeling
 

hi.i want to model a solar air heater.im in the cfx setup.but i have a problem with modeling solar radiation. i make a surface and create a radiation for it.totally i make 3 solid :fluid,plate,radiation plate.in set up i make a plate with thermal radiation monte carlo. my plate Temperature is vary by solar radiation.but in setup of cfx for boundary details,cfx said that you must set a fixed temperature and plate only receive radiation.what should i do?

Can you post an image of what you are trying to model and your CCL file or output file.

thanks for answering.but the size of file is big what part i attach it.but see this images this is my file images .

the outline image
the problem

What is the object floating in space? Radiation needs a domain to propagate through.

now what should i do?i should make a room with air for radiation?or make domain interface for solid?:confused:

Have a look at the tutorials for how to set up radiation models. The combustion in a can combustor is one to look at.
