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.
