Dick Guest Posts: n/a	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
