discretize.operators.InnerProducts.face_areas

property InnerProducts.face_areas

Return areas of all faces in the mesh.

Calling this property will compute and return the areas of all faces as a 1D numpy array. For structured meshes, the returned quantity is ordered x-face areas, then y-face areas, then z-face areas.

Returns:

(n_faces) numpy.ndarray

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

• 1D: returns the x-face areas

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

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