Hi,

I did a chtMultiRegionSimpleFoam case with radiation, convection and conduction between 4 solids and the air around. This model works fine in 2D with frontAndBack with "empty" condition, but when I did the same in 3D I have a problem. The calcul doesn't run ! There is only one iteration and only for displacement solver. The run stopped before h is calculated.

Do you know where the problem could be?
