Many chemical mechanisms contain detailed descriptions of the chemistry, sometimes running to thousands of species and tens of thousands of reactions. However, the time taken to integrate the chemical rate equations is often the single most CPU intensive operation in a reactive simulation and typically scales quadratically with the number of species in the mechanism.

The kinetics & SRM Engine Suite now offers a new Mechanism Reduction post-processing feature. This new feature enables the development of smaller mechanisms that may be used to reduce the CPU time for simulations of practical devices. The reduced mechanisms will retain sufficient detail to be predictive for the cases of interest, but should no longer contain superfluous detail that unnecessarily slows down the simulations.
