P1 radiation model convergence problem with DPM, BERL combustor
 

Hi,

I am simulating a BERL combustor using DPM with an oil injection, radiation models DO and P1.

My simulations work perfectly with an oil injection, gas mass flow and DO radiation model. But P1 model doesn't work with the combination of DPM and gas flow.
However, P1 works only with DPM (i.e. NO gas). Whenever i introduce gas, the simulations diverge.

Can anyone please address this.
