# TS_PVode

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

### Options Database

| -ts_pvode_type <bdf,adams> | - . -ts_pvode_gramschmidt_type <modified, classical> - type of orthogonalization inside GMRES
| -ts_pvode_atol <tol> | - Absolute tolerance for convergence
| -ts_pvode_rtol <tol> | - Relative tolerance for convergence
| -ts_pvode_linear_tolerance <tol> | - . -ts_pvode_gmres_restart <restart> - Number of GMRES orthogonalization directions
| -ts_pvode_not_exact_final_time | - Allow PVODE to stop near the final time, not exactly on it

Notes: This uses its own nonlinear solver and Krylov method so PETSc SNES and KSP options do not apply only PETSc PC options
