splinepy.helpme.integrate.Integrator.physical_function

Integrator.physical_function(function, orders=None)

Integrate a function defined within the physical domain

Parameters:

• spline (Spline) – The geometry over which the function is integrated

• function (Callable) – The user-defined function to integrate. Can also be vector-valued

• orders (optional) – Quadrature order in parametric domain for numerical integration

Returns:

integral – The computed integral. It is vector-valued if function is vector-valued

Return type:

np.ndarray
