Field where field elements are arranged in a 3 dimensional array. Usually represents a field over a structured 3D mesh.
Elements can be accessed either through a single index running over all elements of the array, or by 3 indices indexing elements in 3 basic directions of the grid. The first index ("x direction") ie least significant and the last index is most significant.
