modelRod
Elastic massive rod
Extends from Ports.Compliant (Compliant two-flange).
Information
Translating elastic massive rod. It is equivalent to a massive spring.
(Approximation for small strain / lowest mode to avoid wave-equation)
The parameter stiffness is a length-independent specification, in contrast to a spring-constant.
