pathsim.solvers.esdirk54 module

class pathsim.solvers.esdirk54.ESDIRK54(*solver_args, **solver_kwargs)[source]

Bases: DiagonallyImplicitRungeKutta

7 stage 5-th order L-stable and stiffly accurate ESDIRK method with embedded 4-th order method for stepsize control. This integrator is suited for moderately stiff problems that require high accuracy. The first stage is explicit, followed by 6 implicit stages.
