:orphan: # DMTSGetI2Jacobian get `TS` implicit Jacobian evaluation function for 2nd order systems ## Synopsis ``` #include "petscts.h" PetscErrorCode DMTSGetI2Jacobian(DM dm, TSI2Jacobian *jac, void **ctx) ``` Not Collective ## Input Parameter - ***dm -*** `DM` to be used with `TS` ## Output Parameters - ***jac -*** Jacobian evaluation function, for calling sequence see `TSSetI2Jacobian()` - ***ctx -*** context for Jacobian evaluation ## Note `TSGetI2Jacobian()` is normally used, but it calls this function internally because the user context is actually associated with the `DM`. ## See Also [](ch_ts), `DM`, `TS`, `DMTSSetI2Jacobian()`, `TSGetI2Jacobian()` ## Level advanced ## Location src/ts/utils/dmts.c --- [Edit on GitLab](https://gitlab.com/petsc/petsc/-/edit/release/src/ts/utils/dmts.c) [Index of all TS routines](index.md) [Table of Contents for all manual pages](/manualpages/index.md) [Index of all manual pages](/manualpages/singleindex.md)
