Problems with S2S-Radiation Model

Hello,
I'm working on an Temperature-Calculation of an Multi-Region-Problem (some solids and fluid areas). As boundary conditions are temperatures form -104°C to 30 °C given. A part of the task is to investigate the influence of thermal radiation (which I think is not so big). So I build my model (1 mesh continuum / Polyhedral with embedded thin mesher). The first solutions works very well. The residuas converges and the temperaturas sounds very realistical. After that I implemented the S2S-Radiation model for the fluid regions. So the Energie-balance doesn't converge (see picture) and the temperature rises at some points over 60°C. Does anybody have an idea whats wrong with my model? I have already limit the temperatures and start iteration without radiation and then switched radiation on. |

hi TLH,
could you explain how you activated S2S model for fluid domain? |
