# discretize.CylindricalMesh.face_x_areas#

property CylindricalMesh.face_x_areas#

Areas of each x-face for the entire mesh.

This property returns a 1D vector containing the areas of the x-faces of the mesh. The surface area takes into account curvature. For a single x-face at radial location $$r$$ with azimuthal width $$\Delta \phi$$ and vertical width $$h_z$$, the area is given by:

$A_x = r \Delta \phi h_z$
Returns
(n_faces_x) numpy.ndarray

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