Hello all,

I am trying to add the radiation effect using the discrete ordinates model using the composition PDF method in FLUENT.

When I enabled the DO/Energy coupling, I got an error:
"The DO/Energy coupling option should not be used when the composition PDF transport model is enabled".

We enabled it to accelerate the convergence of the finite volume scheme for radiative heat transfer and can be used with the gray or non-gray radiation model.

My question is why we can't enabled that option?
Does this effect my results?

Thanks in advance.
