  - Absolute Nodal Coordinate Formulation
    The Absolute Nodal Coordinate Formulation or the ANCF is a finite element based representation of flexible components in one, two and three dimensions that are allowed to deform under applied load. It is a formulation that allows you to model Non Linear Flexible Element (NLFE) components in your multibody system.
  - Pre-processing: Use the ANCF to Model Flexible Components
    The implementation of the ANCF in MotionSolve allows you to create flexible components and attach them to the rest of your system in a similar way as rigid bodies.
