Hello
I am trying to model a porous zone in Fluent (the fluid in void is air) which is opaque to thermal radiation. If I set it as a porous zone with air as the media, Fluent treats it as a transparent zone and the thermal radiations do not interact. The zone is only opaque if I set it as a solid zone (with boundary condition set to wall), however in this case air won't flow through it.
Is there a way to combine them, to model a zone which is porous while also being opaque to thermal radiation (regardless of whether it exists in real life situation or not).
Thanks
