# discretize.CylindricalMesh.face_z_areas#

property CylindricalMesh.face_z_areas#

z-face areas for the entire mesh

This property returns a 1D vector containing the areas of the z-faces of the mesh. The surface area takes into account curvature. For a single z-face at between $$r_1$$ and $$r_2$$ with azimuthal width $$\Delta \phi$$, the area is given by:

$A_z = \frac{\Delta \phi}{2} (r_2^2 - r_1^2)$
Returns
(n_faces_z) numpy.ndarray

A 1D array containing the z-face areas for the entire mesh
