Dear Foamers，

I'm trying to use fireFoam + DES+ PaSR to simulate the flow and combustion inside the channel, that is,of course， the interaction between vortex and flame front.

And,now the biggest problem is that I can run both fireFoam + LES + PaSR and reactingFoam + DES + PaSR. But fireFoam + DES + PaSR can't ignite normally.

To be exact, I have tried various ignition method of setfields and fvOptions for several days, but they have not been successful.

At present, it is normal for fireFoam + LES + PaSR to simulate cold flow (pure flow without ignition and combustion).

So, to sum up, my question is: is fireFoam + DES+ PaSR feasible?

Thank you for your attention.

I evenly set the inlet temperature to 2000K, but there is still no chemical reaction, that is to say, the ignition is still not successful.

Any help and Suggestion?

Thank you all.
