Radiation with combustion

Post by Meskine »

Hello all

I try to activate the radiation combined to the combustion. The combustion without radiative module work well. I built a simple case : a hexa mesh 14*14m with a gas fuel flow at the center of ground. I set imodak to 1 in usray1 and I edited usray2 with only the ground as grey wall with fixed internal temperature.

here the error message :

It's seems that there is a problem with the source term.

I am using cs 2.0-rc2 and the d3p model for combustion

Thanks

I found the solution !

It is, actually, a warning message of development progress. It only appears when you use diffusion flame or eddy break up models.

You have to comment "call csexit(1)" in the ppcads routine (line 228) you find in the code saturne kernel and place in the SRC file.

ps : ppcads routine determine the absorption coefficient from combustion (thermochemical data)
