# Configuring tangential behavior for connector friction

 You can select a friction formulation for predefined and user-defined connector friction models. You use the Tangential Behavior tabbed page in the connector section editor to make the selection. For more information, see Using the basic Coulomb friction model. You can choose from the following: Penalty. Specify a friction coefficient. Static-Kinetic Exponential Decay. Specify separate static and kinetic friction coefficients with a smooth transition zone defined by an exponential curve. This task shows you how to:
