This data record may be used to input an additional linear structure stiffness matrix in the global fixed frame. If the analysis includes stage 2 the matrix will be re-set to zero and must be re-defined. If the NASF option is used (Administration and Calculation Options for the Aqwa Suite), this matrix will not be included in the analysis.

(2) The data on this data record defines one row of a stiffness matrix coupling this structure to the one indicated on the WFS* data record in the data category keyword (referred to here as Structure#1). If this is zero or omitted, Structure#2 is set to be the same as Structure#1. Otherwise this number must not be less than Structure#1.

(3) This number indicates which row of the stiffness matrix the values input in columns 21-80 relate to.

(4)-(9) These are the values for the row (3) in the 6x6 additional structure stiffness sub-matrix. The units for angles are radians.

If there are multiple SSTF data records defining the same terms in the stiffness matrix, the values are summed.
