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