how to make 2D axisymmetry with Radiation in Participating Media ?

Why I can't chose Radiation in Participating Media in axisymmetry ?
or
Can I change the coordinate?
Like initial I chose the 2D coordinate.
Then I modify the equation , let it became 2D-axisymmetry.

Hi

Indeed, it's not in the 2D-axi physics options, I cannot tell why like that, need some more thinking, but have you checked carefully the doc ?,
either it has not (yet) been implemented, or it's that the 2D-axi symmetry does not allow for any simple implementation, hopefully it's the first case, and it might arrive in next release. But "support" can certainly tell you why

Good luck
