Summary0003681: chtMultiRegionFoam: consideration of radiation leads to error
DescriptionIn the example attached, hot air enters at the inlet. The wall (solid) is heated in the process. The radiation was also taken into account (P1 model). The minimum and maximum temperature of the patch "air_to_solid" is also recorded (files: maxT.png, minT.png) . After a certain time the temperature of the patch "air_to_solid" starts to fluctuate and the program ends with an error.
