discretize.CylindricalMesh.face_z_areas#

property CylindricalMesh.face_z_areas#

Areas of each z-face 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 $\mathrm{\Delta }\varphi$, the area is given by:

$$A_z=\frac{\mathrm{\Delta }\varphi }{2}(r_2^2-r_1^2)$$

Returns:

(n_faces_z) numpy.ndarray

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