| -ts_sundials_type <bdf,adams> | - | |
| -ts_sundials_gramschmidt_type <modified, classical> | - type of orthogonalization inside GMRES | |
| -ts_sundials_atol <tol> | - Absolute tolerance for convergence | |
| -ts_sundials_rtol <tol> | - Relative tolerance for convergence | |
| -ts_sundials_linear_tolerance <tol> | - | |
| -ts_sundials_maxl <maxl> | - Max dimension of the Krylov subspace | |
| -ts_sundials_monitor_steps | - Monitor SUNDIALS internal steps |
Notes: This uses its own nonlinear solver and Krylov method so PETSc SNES and KSP options do not apply, only PETSc PC options.
