        Parameters
        ----------
        stepName
            A String specifying the name of the step in which the surface offset assignments are to 
            be modified. 
        index
            An Int specifying the position of the surface offset fraction assignment whose value is 
            to be modified. 
        value
            A tuple specifying the value of the surface offset assignments for the surface whose 
            index is referenced. Each tuple contains one entry: 
            - A Float or a SymbolicConstant specifying the surface offset fraction value to be used 
            for the surface. Possible values of the SymbolicConstant are ORIGINAL, SPOS, and SNEG.

        Parameters
        ----------
        stepName
            A String specifying the name of the step in which new surface offset fraction 
            assignments are to be defined. 
        assignments
            A sequence of tuples specifying the surface offset fraction assignments. Each tuple 
            contains two entries: 
            - A region or a material object or the SymbolicConstant GLOBAL specifying the surface to 
            which the offset fraction is assigned. 
            - A Float or a SymbolicConstant specifying the surface offset fraction value to be used 
            for the surface. Possible values of the SymbolicConstant are ORIGINAL, SPOS, and SNEG.
