Issue of FvDOM radiation model in 2D axisymmetric case
 
1 Attachment(s)
Hi,

I am running a 2D axisymmetric case using wedge grid, there are two wedge boundaries and one axis boundary. I am using fvDOM radiation model to calculate the radaition heat loss from the high temperature gas.

I got a very very high value of I (radiation intensity) and G (incident radaiton) in Axis (see the attachment). My guess is that fvDOM had a problem when it encountered the boundary condition of Axis. The ray should have passed through Axis, but it did not.

Does anyone know how to solve this issue? I really appreciate.

Regards,
Junjun
