Structured Grid (IJK) : Definition Data Records

 A Structured Grid (IJK) Definition Data Set is denoted by a `KEY' of 60 in the data set header record. The grid definition data comprises a header record of the form:

KEY, NUMBLK, IDIMEN

To be written with the format:

FORMAT (1X, I2, 2I10)

Where:

KEY = -1 for the data header record -3 for the data set delimiter record which is an otherwise blank record inserted at the end of the data set.

NUMBLK = Number of blocks in the model.

IDIMEN = If the grid is 2D or 3D. 1 = 3D 2 = 2D in the IJ plane. (Note other 2D planes not yet supported)

Then, for each block, followed by a data continuation record of the form:

KEY, I, J, K

To be written with the format:

FORMAT (1X, I2, 3I10)

Where:

KEY = -2 for a data continuation record.

I = Number of cells in the I direction.

J = Number of cells in the J direction.

K = Number of cells in the K direction.
