[petsc-users] Checkpointing / restart

[Carles Bona]

Dear all,

I am trying to restart a TS calculation from a previously saved result.
However, when I call TSSolve I can only provide the saved solution vector
(U) as an initial condition, but I haven't found a way to set the initail
time derivative (V) through a call to TSSolve.

Is there a way do this? Which would be the way to restart from a
checkpointed state?

Many thanks,

Carles
