pathsim.solvers.ssprk34 module

class pathsim.solvers.ssprk34.SSPRK34(*solver_args, **solver_kwargs)[source]

Bases: ExplicitRungeKutta

Four-stage, 3rd order, Strong Stability Preserving (SSP) explicit Runge-Kutta method.

Provides a larger stability region compared to SSPRK33, particularly along the negative real axis, at the cost of an additional stage. Useful when stability is more critical than computational cost for a 3rd order explicit method.

Characteristics:

  • Order: 3

  • Stages: 4

  • Explicit (SSP)

  • Fixed timestep only

  • Enhanced stability compared to SSPRK33.
