To Enable All Friction
By selecting or clearing the Enable all friction check box on the External loads tab of the Analysis Definition dialog box, you indicate whether the friction coefficients that you specified for cam-follower, slot-follower or connection sets in dynamic or force balance analyses will be used.
The Enable all friction check box is not selected by default. When it is selected, any friction coefficients that you enabled for cam-follower, slot-follower, or connection sets are used for the analysis. If you clear the Enable all friction check box, no friction is applied during the analysis even if you included it in the connection definition.
