Returns the areas of all cell faces.

Calling this property will compute and return the areas of all mesh faces as a 1D numpy array.

(n_faces) numpy.ndarray

The length of the quantity returned depends on the dimensions of the mesh:

  • 2D: returns the x-face and y-face areas; i.e. y-edge and x-edge lengths, respectively

  • 3D: returns the x, y and z-face areas in order
