[petsc-users] Setting TimeStep in TS

[Smith, Barry F.]

  I don't understand. One of the arguments to your TSPseudoSetVerifyTimeStep() routine is the "update - latest solution vector" but you seem to want access to the "next" solution that has yet to be computed? There is no way to access that because it has not yet been computed and cannot be computed until the next time step has been decided on.

However, it is called before TimeStep routine. Is there any way that I can access to new solution, while I can set the the time step?
