This option allows you to choose between performing a classic friction analysis with sliding-to-sticking and sticking-to-sliding transitions by setting its value to Friction with Sliding/Sticking Transitions or Program Controlled. You can perform a pure sliding friction analysis by setting its value to Forced Frictional Sliding.
For revolute, translational and cylindrical joints, its default value is Program Controlled.
Note:
For point-on-curve, spherical, slot, universal, and general joints, only Forced Frictional Sliding is available.
The Forced Frictional Sliding behavior enables a smoother simulation, since there is no need to search for transition events. This might save simulation time if advanced friction modelling is not required.
