Setting up the Models

The Complex Chemistry model is used with the Segregated Flow model to simulate the turbulent reacting flow of a compressible multi-component gas.

  1. For the physics continuum, Continua > Physics 1:
    1. In the Enabled Models group box, deactivate Two Dimensional.
    2. Make sure that Auto-select recommended models is activated and select the following models in order:
