        Parameters
        ----------
        stepName
            A String specifying the name of the step in which the surface thickness assignments are 
            to be modified. 
        index
            An Int specifying the position of the surface thickness assignment whose value is to be 
            modified. 
        value
            A tuple specifying the value of the surface thickness assignments for the surface whose 
            index is referenced. Each tuple contains two entries: 
            - A Float or a SymbolicConstant specifying the overriding thickness value to be used in 
            the contact definition. Possible values of the SymbolicConstant are ORIGINAL and 
            THINNING. The SymbolicConstant THINNING can be specified only in an Abaqus/Explicit 
            analysis. 
            - A Float specifying a scale factor that multiplies the thickness value specified in the 
            second entry.

        Parameters
        ----------
        stepName
            A String specifying the name of the step in which new surface thickness assignments are 
            to be defined. 
        assignments
            A sequence of tuples specifying the surface thickness assignments. Each tuple contains 
            three entries: 
            - A region or a material object or the SymbolicConstant GLOBAL specifying the surface to 
            which the thickness is assigned.

            the contact definition. Possible values of the SymbolicConstant are ORIGINAL and 
            THINNING. The SymbolicConstant THINNING can be specified only in an Abaqus/Explicit
