        Parameters
        ----------
        stepName
            A String specifying the name of the step in which the surface crush trigger assignments 
            are to be modified. 
        index
            An Int specifying the position of the surface crush trigger assignment whose value is to 
            be modified. 
        value
            A tuple specifying the value of the surface crush trigger assignments for the surface 
            whose index is referenced. Each tuple contains three entries: 
            - A SymbolicConstant specifying the trigger option to be used for the surface. Possible 
            values of the SymbolicConstant are TRIGGER, NO_TRIGGER, or NO_CRUSH. 
            - A Float specifying the crush stress value to be used for the surface. 
            - A Float specifying the crush initiation angle value to be used for the surface. 
            - A Float specifying the crush continuation angle value to be used for the surface.

        Parameters
        ----------
        stepName
            A String specifying the name of the step in which new surface crush trigger assignments

        assignments
            A sequence of tuples specifying the surface crush trigger assignments. Each tuple 
            contains four entries: 
            - A region or a material object or the SymbolicConstant GLOBAL specifying the surface to 
            which the feature angle is assigned.

            values of the SymbolicConstant are TRIGGER, NO_TRIGGER, or NO_CRUSH.
