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 \(\Delta \phi\), 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
