Arguments

gcon_name: The variable name of the general constraint.; Data type: varname
USER: Indicates that the general constraint is of a user subroutine type.; Data type: keyword
expr: A string that the solver input deck will use to invoke the user subroutine.; Data type: string

Example

*BeginMDL( the_model, "Model", )
 *StandardInclude(FILE)
 *SetCurrentSolverMode(MotionSolve)
 *Body( b_0, "Body 0", , , , , )
 *Body( b_1, "Body 1", , , , , )
 *Point( p_1, "Point 1" )
 *Point( p_2, "Point 2" )
 *Marker( m_0, "Slot", b_1, p_2 )
 *Marker( m_1, "Point", b_0, p_1 )
 *GeneralConstraint( gcon_0, "GeneralConstraint 0" )
