Hi All,

I am sure many of you would have come across the need for adaptive time-stepping. Is there any provision in OpenFOAM to do that. Any simple algorithm will do.

For e.g. if the velocity does not converge. Start again from the previous time step value with a reduced time step = (some factor)(current time step). Likewise for increase of time step.

Check out e.g. interFoam (setD
Check out e.g. interFoam (setDeltaT.H). It has dynamic timestep control (based on previous time step Courant number)
