I would like to model radiation in 2D using CFX. How can I do this? I have a mesh 2 cells thick, bounded by symmetry planes.

Radiation in 2D works fine and the radiation incident on the symmetry planes will undergo a mirror reflection with angle of reflection = angle of incidence. With the Monte Carlo method, you might get a message that the paths are too long if the distance between the two symmetry planes is too small. To fix this, simply increase the distance between the symmetry planes (since this has no physical significance in a 2-D approximation).
