# MPC

 User subroutine to define multi-point constraints. User subroutine MPC: is called to impose a user-defined multi-point constraint and is intended for use when general constraints cannot be defined with one of the MPC types provided by Abaqus/Standard; can use only degrees of freedom that also exist on an element somewhere in the same model (methods for overcoming this limitation are discussed below); can generate linear as well as nonlinear constraints; allows definition of constraints involving finite rotations; and makes it possible to switch constraints on and off during an analysis. The following topics are discussed:
