Gauss Point Coordinates

  This data set is used to define the coordinates of element gauss points. Currently this data set is used only for the display of local axis systems at element gauss points. For results at element Gauss points the Gauss point coordinates must be input with the results data. A Gauss Point Coordinate Data Set is denoted by a `KEY' of 30 in the data set header record. For each element for which Gauss point coordinate data is given there is a header record of the form:

KEY, NUMB, ITYPE, IGROUP, NODAL, NSURF, INTEG

To be written with the format:

FORMAT(1X, I2, 5I5)

or: FORMAT (1X, I2, I10, 4I5) for 10 digit element number format

Where:

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

NUMB = element number.

ITYPE = FEMVIEW element type (optional).

IGROUP = element group number.

NODAL = 0

NSURF = number of surfaces (outer repeat).

INTEG = number of Gauss points (inner repeat).

Followed by data continuation records of the form:

KEY, IGPNT, X, Y, Z

To be written with the format:

FORMAT(1X, I2, I5, 3E12.5)

Where:

KEY = -2 for a data continuation record.

IGPNT = Gauss point number.

Z, Y, Z = X, Y and Z coordinates of the gauss point.

Notes:

1.

Gauss Point Coordinates should be input in the same order as the elements are given in the element topology data, but it is not necessary to give coordinates for each element.
