Modeling subroutines are user-written subroutines that allow you define the run-time behavior of a modeling element via a user subroutine. Modeling subroutines are used by various modeling entities, like forces and motions, and other elements directly defined in your multi-body mechanical system.
These are listed below with a brief description of each. See each subroutine’s documentation for more details on its use.
