A short / one-liner example to highlight the (new) feature

multipatch = sp.Multipatch(splines=[bez_el0, rbz_el1, bsp_el2, nur_el3])


# Define some functions for boundary identification
def is_boundary(x):
    return x[:, 0] < 0.01

# Add boundary
multipatch.add_boundary_with_function(is_boundary)

# Test Output
sp.io.gismo.export("test2D.xml", multipatch)
