    Calculate the flexure parameter based on some physical constants. *h* is
    the Effective elastic thickness of Earth's crust (m), *E* is Young's
    Modulus, and *n_dim* is the number of spatial dimensions for which the
    flexure parameter is used. The number of dimension must be either 1, or
    2.
