  3. I am running an EDM model in which the reactants are burning too close to my nozzle. I enabled beta features and used the TUI control for temperature limits on reaction to control my lower temperature limit /define/models/species> species transport expert Minimum cell temperature for kinetics calculations [200] 800 but it had no effect. What am I doing wrong?

      Only kinetics calculations are suppressed by this control. EDM Turbulent rates will still be non-zero. To prevent burn-back, run a combination of Finite Rate and EDM in conjunction with this control. The minimum rate at lower temperatures wll typically be the Chemical rate; this will be applied and then curbed by the expert parameter.
