Detailed Description

In a finite-volume, Cartesian partition of the computational domain, several types of nodes are defined:

CELL_CENTERED at the center of the cell,

X/Y/Z_FACE_CENTERED at the center of the x/y/z faces of the cells,

X/Y/Z_EDGE_CENTERED at the center of the x/y/z edges of the cells,

VERTEX_CENTERED at the vertices.

This module defines a node_type derived type whose instances represent one of the node type.

Every node type has a dual. The function get_dual_node_type returns the dual of the node_type given as argument. In 2D, the function get_two_d_node_type should also be used.

Equality comparisons can be done with operators == and /=.

Coordinates, cell step and indice ranges can be retrieved by passing the node type instance to the routines of the module generic_node_type.
