Get flow
--------------
Set the initial time, retrieve a jit-callable for the flow, and set up domain.

.. GENERATED FROM PYTHON SOURCE LINES 20-34

.. code-block:: Python


    # set time at which to compute iLE
    t0 = 0.0

    # retrieve function pointer, parameters, and domain for double gyre flow.
    vel_func, domain = get_predefined_callable("double_gyre")

    # set up domain
    nx, ny = 401, 201
    x = np.linspace(domain[0][0], domain[0][1], nx)
    y = np.linspace(domain[1][0], domain[1][1], ny)
    dx = x[1] - x[0]
    dy = y[1] - y[0]

iLE
---------
Compute iLE from velocity function at t = t0.
