Information

1. Simulate and then plot stop1.f as a function of stop1.v This gives the Stribeck curve.
2. The same model is also available by modeling the system with a Mass and a SupportFriction model. The SupportFriction model defines the friction characteristic with a table. The table is constructed with function Examples.Utilities.GenerateStribeckFrictionTable(..) to generate the same friction characteristic as with stop1. The simulation results of stop1 and of model mass are therefore identical.
3. Model stop2 gives an example for a hard stop. However there can arise some problems with the used modeling approach (use of reinit(..), convergence problems). In this case use the ElastoGap to model a stop (see example Preload).
