TSSUNDIALS#

ODE solver using a very old version of the LLNL CVODE/SUNDIALS package, version 2.5 (now called SUNDIALS). Requires ./configure –download-sundials

Options Database Keys#

  • -ts_sundials_type <bdf,adams> -

  • -ts_sundials_gramschmidt_type <modified, classical> - type of orthogonalization inside GMRES

  • -ts_sundials_atol - Absolute tolerance for convergence

  • -ts_sundials_rtol - Relative tolerance for convergence

  • -ts_sundials_linear_tolerance -

  • -ts_sundials_maxl - Max dimension of the Krylov subspace

  • -ts_sundials_monitor_steps - Monitor SUNDIALS internal steps

  • -ts_sundials_use_dense - Use a dense linear solver within CVODE (serial only)

Note#

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