[petsc-users] setting Sundials options within petsc4py

[Veltz Romain]

Dear pets users,

I have been trying to set some sundials options from petsc4py but I am unsuccessful. I hope somebody will have a good pointer.
For example I can pass -ts_sundials_type bdf to python in the command line.

I would like to call TSSundialsSetTolerance to set the tolerance. Hence I need to pass some options in the command line (I don't know if this is possible for this particular function) or call TSSundialsSetTolerance(…) from petsc4py. So far, I am clueless.

Also, I would like to limit the step sizes. This is not documented in petsc_manual.pdf. But in sundial.c, there is PetscErrorCode  TSSundialsSetMaxTimeStep_Sundials(TS ts,PetscReal maxdt) which I would like to call also from petsc4py.

Thank you for your help,

Best regards,


Veltz Romain
