Can't impose radiation in the coupling simulation

[Jundi He]

Hi:

I have a coupling simulation and it can run without considering the radiation. But now I need to considering the radiation, and after I input all the radiation properties, and run the simulation, it stops at "radiation initialization 100%", here is the screenshots and listing file. I wonder what's the problem, many thanks!

Best Regards!

And this is the listing file and the screenshot when I run the case. Thanks!

By the way, I use the same mesh for the conduction and radiation, does it matter? Thanks!

Hi:

I tried to use another simple mesh for the radiation, and run the case again, it also stops at the radiation initialization step. This is the screenshot and the listing file. Thanks for the time.

Best Regards!

Hi:

I've solve the problem. At first I didn't know that the radiation mesh is a shell between the solid, and I need to couple the face of radiation and conduction meshes. Thank you!
