Detailed Description

Functions to compute (x1,x2,x3) positions of cells i,j,k.

PURPOSE: Functions to compute (x1,x2,x3) positions of cells i,j,k. In a nested grid, each Grid structure is a patch in a larger computational domain (with the exception of the level0 grid). The displacement of the origin of the Grid from the origin of the computational domain (level0 grid) is x1_{disp} = idisp*dx1. Furthermore, the origin of the level0 grid can be displaced by a distance x1_{0} from the origin of x1. Thus, the x1 position of the center of cell i (x1_{cc,i}) in any level Grid is x1_{cc,i} = x1_{0} + ((i + idisp) + 0.5)*dx1 Similarly for x2 and x3.

CONTAINS PUBLIC FUNCTIONS:

cc_pos() - given i,j,k returns cell-centered x1,x2,x3
fc_pos() - given i,j,k returns face-centered x1,x2,x3
x1cc() - given i, returns cell-centered x1.
x2cc() - given j, returns cell-centered x2.
x3cc() - given k, returns cell-centered x3.
celli() - given x, returns containing cell first index.
cellj() - given y, returns containing cell first index.
cellk() - given y, returns containing cell first index.
