Remarks
- Element identification numbers must be unique with respect to all other element identification numbers.
- A blank may be used to indicate a grounded terminal G1 or G2 with a corresponding blank or zero C1 or C2. A grounded terminal is a point whose displacement is constrained to zero.
- This single entry completely defines the element since no material or geometric properties are required.
- The two connection points (G1, C1) and (G2, C2), must be distinct.
- If Gi refers to a grid point, then Ci refers to component numbers in the displacement coordinate system specified by CD on the GRID entry.
