Hýr0 is on a distinguished road
Hi,
I would to know if combustion occurs at constant pressure in ReactingFoam? I'm confused looking at the code, I don't understand the logical sequence in this model.

0(internalField: p0,T)0 -> reactions(therm_dat.chemkin.inp):Yi,Ti,hs -> GasPerfect: psi=1/RT -> basicPsiThermo(p const):rho=p*psi -> hmix=f(hs,psi) -> then how updates p at next time step...solving p equation????

which is the difference with rhoReactiongFoam?

Please help me!Thanks
