CFX - Stiff Chemistry
Hi guys! Have anybody an experience of using "stiff chemistry" (hidden beta feature) in CFX 11? Or may be some tips of using FRC model for combustion simulation with detailed kinetics (H2/O2 burner with 11 step mechanism)? I`ve got a problem with it - very small timestep (1e-8 s) that makes me think that it is impossible :(
