Structs

BlockDiff

Differencing data at a single node in a 3D block.

FaceDiff

Differencing data at a single node on a 2D face.

Functions

find_edges

Compute forward and backward differences along each direction for a 3D block.

find_face_edges

Compute forward and backward differences along each direction for a 2D face.
