You must include a parameter table of type "ABQ_EChemPET_CubicSplineC2" in the material definition to specify the material curve as a cubic spline over equal interval sizes. Each interval is fitted with a cubic spline equation of the form y(x) = C 3 ( x - x i ) 3 + C 2 ( x - x i ) 2 + C 1 ( x - x i ) + C 0 .

Repeat the parameter table data lines as needed to specify the coefficients of spline interpolation for all intervals covering the full range of the material curve.
