For astrophysical reacting flows, operator splitting is commonly used tocouple hydrodynamics and reactions. Each process operates independent of oneanother, but by staggering the updates in a symmetric fashion (via Strangsplitting) second order accuracy in time can be achieved. However,approximations are often made to the reacting system, including the choice ofwhether or not to integrate temperature with the species. Here we demonstratethrough a simple convergence test that integrating an energy equation togetherwith reactions achieves the best convergence when modeling reactive flows withStrang splitting. Additionally, second order convergence cannot be achievedwithout integrating an energy or temperature equation.
