As a novice user I am experimenting with simple mechanical components and assemblies mostly with good success.
A model with an Engine, Gear and Clutch driving an inertia solves without problems and in accordance with expectations including transition to clutch slip as clutch pressure is reduced. An identical model with the Gear replaced by a (Driveline) Variable Ratio Transmission will not solve into the slip region giving a "failure to converge error". I have tried different solvers, reduced time steps, modified clutch parameters and added dampers but with no success.
Has anyone got any ideas?
