error on non-premixed turbulent combustion
 
Hi everybody, I have a problem with a simulation of a steady turbulent reactive flow in a combustor. I brought the "cold" simulation to convergence, and when I try to run the reactive simulation (with non-premixed flamelet model) an error appears: "PDF All No species: unable to get properties". I'm using methane as fuel and air as oxidizer (the loaded reaction mechanism has 17 species); the turbulence model is the realizable k-epsilon, and the geometry has a rotational periodicity. The same geometry was been previously calculated using hydrogen as fuel without problems. Can someone help me please? Thanks a lot.

I've solved the problem using a different chemical kinetic mechanism. Probably the previous mechanism I used was not apt to the conditions of calculation, specially at operating pressure.
