e.g. in the reactingFoam/laminar/counterFlowFlame2DLTS tutorial: PIMPLE { momentumPredictor no; nOuterCorrectors 1; nCorrectors 1; nNonOrthogonalCorrectors 0; maxDeltaT 1e-2; maxCo 1; alphaTemp 0.05; alphaY 0.05; Yref { O2 0.1; ".*" 1; } rDeltaTSmoothingCoeff 1; rDeltaTDampingCoeff 1; } will limit the LTS time-step according to the rate of consumption of 'O2' normalized by the reference mass-fraction of 0.1 and all other species normalized by the reference mass-fraction of 1. Additionally the time-step factor of 'alphaY' is applied to all species. Only the species specified in the 'Yref' sub-dictionary are included in the LTS limiter and if 'alphaY' is omitted or set to 1 the reaction rates are not included in the LTS limiter. |
