__init__(variables)

Methods

__init__(variables)
run(t, dt[, t0, jacobian, show_progress])	Run the simulation.
set_diff_eq(calc_diff_eqs, params, ...)	Set the differential equation function.
set_integration_method([method])	Set the integration method.

Attributes

run(t, dt, t0=0.0, jacobian=None, show_progress=False)

Run the simulation.

Parameters:

• t (float) – Final time

• dt (float) – Timestep

• t0 (float) – Initial time (default 0.0)

• show_progress (bool) – Show a progress bar for the integration.

set_diff_eq(calc_diff_eqs, params, ini_conds, events)

Set the differential equation function.

Parameters:

• calc_diff_eqs – Callable returning dy/dt

• **kwargs – Additional arguments passed to the function

set_integration_method(method='RK45')

Set the integration method.

Parameters:

method (str) – Integration method name.
