Solver parameters

Solver parameters are technical parameters that modify the solver procedure. They are passed directly to scipy.integrate.solve_ivp. All of the parameters have default values which are used unless specified otherwise.

solver.method

Type:

string

Default:

“RK45”

Integration method to use. Alternatives are “RK45”, “RK23, “DOP853”, “RADAU”, “BDF” and “LSODA”.

solver.rtol

Type:

number

Default:

1e-3

Relative tolerance. The solver keeps the local error estimates less than atol + rtol * abs(y).

solver.atol

Type:

number

Default:

1e-6

Absolute tolerance. The solver keeps the local error estimates less than atol + rtol * abs(y).

solver.first_step

Type:

number

Default:

0

Initial step size. Default is 0 which means that the algorithm should choose.

solver.max_step

Type:

number

Default:

0

Maximum allowed step size. Default is 0 which means that the step size is not bounded and determined solely by the solver.
