# TSSUNDIALS

ODE solver using the LLNL CVODE/SUNDIALS package (now called SUNDIALS)

### Options Database

| -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.
