[petsc-users] Information about TSAdapt

[Pierre Barbier de Reuille]

Hello,

I have issues with the adaptive time stepping when using theta methods. The
time step selected is extremely really small, much smaller than the time
step selected by the explicit runge-kutta methods (2 or 3 order of
magnitude smaller!).

To try understand what is going on, I would like to have information on
what is done for the basic adaptive time stepping (which is the one I
started using). Also, any help on what is recommended as time-stepping goes
would be great.

Thanks,
