[petsc-users] Finite difference approximation of Jacobian

[Tang, Qi]

Hi,
Does anyone have comment on finite difference coloring with DMStag? We are using DMStag and TS to evolve some nonlinear equations implicitly. It would be helpful to have the coloring Jacobian option with that.

Thanks,
Qi

Hello,

Does the Jacobian approximation using coloring and finite differencing of the function evaluation work in DMStag?
Thank you.
Best regards,

Zakariae
