pathsim.solvers.rkv65 module

class pathsim.solvers.rkv65.RKV65(*solver_args, **solver_kwargs)[source]

Bases: ExplicitRungeKutta

9-stage 6-th order with embedded 5-th order Runge-Kutta method from Verner with 6-th order truncation error estimate.

This is the ‘most robust’ 9, 6(5) pair of Jim Verner’s Refuge for Runge-Kutta Pairs URL: https://www.sfu.ca/~jverner/

Characteristics: * Order: 6 (Propagating solution) * Embedded Order: 5 * Stages: 9 * Explicit * Adaptive timestep * Efficient high-order method for non-stiff problems.
