r1: r*8: Pretension of spring
This card allows the definition of pre-tension for a spring defined by the *DASH card. The resulting spring force equals f = k(u)(u – p). Where, f is the spring force, k is the spring stiffness (defined by *DASH), u the displacement, and p is the spring pretension defined by the r1 value in the *DSHP. *DSHP is used within the *MATE block. Refer to the Units of Measure topic for questions about the units to use for this input.
