[petsc-users] When is the TSMonitor called?

[Miguel Angel Salazar de Troya]

Hi all

I want to save a certain quantity at the very beginning of each time step,
before any TSFunction of any kind is called. Can I do this within the
TSMonitor? It would also be ok to save that quantity at the very end of the
time step.

Thanks
Miguel

This is the main time loop in TSSolve()

while (!ts-reason) {
  ierr = TSMonitor(ts,ts-steps,ts-ptime,ts-vec_sol);CHKERRQ(ierr);
  ierr = TSStep(ts);CHKERRQ(ierr);
  ierr = TSPostStep(ts);CHKERRQ(ierr);
}
