XYZ invokes generation of a Cartesian (rectilinear) mesh.
Record XYZ.l
Free format for 1 parameter or Format (E10.4)
DEG
DEG angle (in degrees) between the Y-axis and the horizontal. If gravitational acceleration (parameter GF in record .2) is specified positive, -90° < DEG < 90° corresponds to grid layers going from top down. Grids can be specified from bottom layer up by setting GF or negative. Default (DEG = 0) corresponds to horizontal Y- and vertical Z-axis. X-axis is always horizontal.
Record XYZ.2
Free format for 3 parameters or Format (A2, 3X, I5, E10.4)
NTYPE, NO, DEL
NTYPE set equal to NX, NY or NZ for specifying grid increments in X, Y, or Z direction.
NO number of grid increments desired.
DEL constant grid increment for NO grid blocks, if set to a non-zero value.
Record XYZ.3 (optional, DEL = 0. or blank only)
Free format for as more as 20 parameters or Format (8E10.4)
DEL(I), I = 1, NO
DEL(I) a set of grid increments in the direction specified by NTYPE in record XYZ.2. Additional records with formats as XYZ.2 and XYZ.3 can be provided, with X, Y, and Z-data in arbitrary order.
Record XYZ.4 a blank record closes the XYZ data block.
Note that the end of block MESHMaker is also marked by a blank record. Thus, when MESHMaker/XYZ is used, there will be two blank records at the end of the corresponding input data block.
