[petsc-dev] Time-Steppers: how to stop and resume iterations at intermediate times?

[Alexis Marboeuf]

Dear Petsc Team,
I am using a TS object to integrate my equation in time. I set the final time 
using TSSetMaxTime. My question is about a proper way to stop and resume 
iterations at intermediate times inside the TSSolve. I would like to stop when 
reaching exactly some given intermediate times, do some work (writing my 
intermediate solution for example) and then resume iterations.
Thanks a lot for your time and your help.
Best,
Alexis
