The mechanism reduction capability in Reaction Workbench relies on Ansys Chemkin to compute the quantities of interest, such as ignition time, flame speeds, and species concentrations. This requires choosing and setting up an appropriate reactor model in Chemkin that most closely describes the kinetics phenomena occurring in your engine and that is able to capture one or many predicted variables of interest. Refer to the tutorial, Mechanism Reduction for Compression Ignition Conditions, in the Reaction Workbench Tutorial Guide for more information. The figure Figure 1.1: Mechanism reduction iterative process shows a schematic overview of the process.
