timflow.steady.model.Model3D.intnormflux_segment
================================================

.. py:method:: timflow.steady.model.Model3D.intnormflux_segment(x1, y1, x2, y2, method='legendre', ndeg=10)

   
   Integrated normal (perpendicular) flux over specified line segment.

   Flux to the left is positive when going from (x1, y1) to (x2, y2).

   :param x1:
   :type x1: float
   :param y1:
   :type y1: float
   :param x2:
   :type x2: float
   :param y2:
   :type y2: float
   :param method: integration method, either "quad" (numerical integration using scipy)
                  or "legendre" (approximate integral using Gauss-Legendre quadrature),
                  by default "legendre".
   :type method: str, optional
   :param ndeg: degree for legendre polynomial, by default 10,
                only used when method="legendre"
   :type ndeg: int, optional

   :returns: **Qn** -- integrated normal flux along specified line
   :rtype: np.array
