The frictionModel command is used to construct a friction model object, which transforms beam element stiffness and resisting force from the basic system to the global-coordinate system. The command has at least one argument, the friction model type. Each type is outlined below.

frictionModel frnMdlType? arg1? ...

---

The type of friction model created and the additional arguments required depend on the frnMdlType? provided in the command.

The following contain information about frnMdlType? and the args required for each of the available friction model types:

• Coulomb Friction
• Velocity Dependent Friction
• Velocity and Pressure Dependent Friction
