The Gauss point co-ordinate dataset is a new development. When using Gauss point local axis systems, this dataset must be present. When using Gauss point results this dataset need not be present, and valid Gauss point co-ordinates must be used with routine DIEGR.

Gauss point co-ordinate data is entered using routines DIGPH and DIGPD. For each element routine DIGPH is called once only, and routine DIGPD is called once for each Gauss point at each surface. The number of Gauss points is the inner repeat, and the number of surfaces is the outer repeat when calling routine DIGPD.
