Are you calling TSSolve() or TSStep()? What version of PETSc?

Dear all,

I use the TSSetPostStep function to apply a function at the end of each time step.
I code the following:

   ierr = TSCreate(sys.comm, &sys.ts);
   CHKERRQ(ierr);

   ierr = TSSetApplicationContext(sys.ts, &sys);
   CHKERRQ(ierr);

   ierr = TSSetProblemType(sys.ts, TS_NONLINEAR);
   CHKERRQ(ierr);

   ierr = TSSetSolution(sys.ts, sys.gsv);
   CHKERRQ(ierr);

   ierr = TSSetPostStep(sys.ts, limiter_implicit);
   CHKERRQ(ierr);

   ierr = TSSetIFunction(sys.ts, sys.gres0, base_residual_implicit, &sys);
   CHKERRQ(ierr);

   ierr = TSGetSNES(sys.ts, &sys.snes);
   CHKERRQ(ierr);

   ierr = MatCreateSNESMF(sys.snes, &sys.J);
   CHKERRQ(ierr);

and in the function :

limiter_implicit set in TSSetPostStep I just put the command: puts("out\n"). But nothing prints on the the output at the end of each step. Any suggestions?
