discretize.CylindricalMesh.cell_volumes

property CylindricalMesh.cell_volumes

Volumes of all mesh cells.

This property returns a 1D vector containing the volumes of all cells in the mesh. When computing the volume of each cell, we take into account curvature. Thus a cell lying within radial distance \(r_1\) and \(r_2\), with height \(h_z\) and with azimuthal width \(\Delta \phi\), the volume is given by:

\[V = \frac{\Delta \phi \, h_z}{2} (r_2^2 - r_1^2)\]

Returns:

(n_cells numpy.ndarray
