61 /* We have two different sets of node: 1. grid node, the physical points
62 where grid lines intercross; 2. storage node, where we store variables.
63 All node without explicitly specified as "grid node" refers to
64 storage node.
65
66 The integer node is defined at cell center while half node refers to
67 the actual grid node. (The reason to choose this arrangement is we need
68 ghost node, which is half node away from boundaries, to specify boundary
69 conditions. By using this storage arrangement, the actual storage need
70 is (IM+1) * (JM + 1) * (KM+1) where IM, JM, & KM refer to the number of
71 grid nodes along i, j, k directions.)
72
73 DA, the data structure used to define the storage of 3D arrays, is defined
74 as mx * my * mz. mx = IM+1, my = JM+1, mz = KM+1.
75
76 Staggered grid arrangement is used in this solver.
77 Pressure is stored at interger node (hence the cell center) and volume
78 fluxes defined on the center of each surface of a given control volume
79 is stored on the cloest upper integer node. */
