Threshold Parameter Tuning
Compare values for the Follower power threshold parameter in the Simple Gear block for a basic mechanical system. Blocks like the Simple Gear block use threshold parameters to smoothly transition a physical characteristic between zero and nonzero. Threshold parameters like the Follower power threshold parameter in the Simple Gear block are a numerical tool that you can use to aid the solver with transition and improve simulation performance. The appropriate value for this parameter depends on the system. You must determine it on a case by case basis by comparing simulation step sizes for a range of values, but the same advice applies to all threshold parameters.
