TSBDF

DAE solver using implicit backward differentiation formula (BDF) methods suitable for stiff ODEs.

Options Database Keys

• -ts_bdf_order - Order of the BDF method

• -ts_bdf_initial_guess_extrapolate <true, false> - Extrapolate the initial guess of the nonlinear solve from previous time steps, defaults to true
