dt and smaller time step
Dear Foamers,
I am wondering how to use dt for some variables and another time steps smaller than dt for other variables. Specifically, dt :0.02 for V1...... and another dt (0.01, 20 increments of dt specified in the control) for other V2...... My best regards, Jian |
Have a look at interFoam: Here we have an extra loop for subcycling of alpha, which means alpha will be solved with a fraction of the regular time step if activated.

Many thanks. But I am wondering how to activate the subcycling of total deltaT. Where can I find the 'pimple.dict()' and the corresponding tutorial case?
.... In the alphaEqnSubCycle.H, label nAlphaCorr(readLabel(pimple.dict().lookup("nAlphaC orr"))); label nAlphaSubCycles(readLabel(pimple.dict().lookup("nA lphaSubCycles"))); |
