[petsc-users] Solve ODE in backward in time

[Koshkarov, Oleksandr]

Hello all,

Can TSSolve be used to solve ODE backward in time? for example from t=10 upto t=5 ? Google search reveals to use TSAdjointSolve, but by reading manual, It looks it is used for sensitivity analysis which I do not need. And I am not sure how to use it to just integrate ODE back in time. I tried to setup final time and/or time step to be negative without success.

Thank you and Happy New Year,

Oleksandr.
