How to set parameters of the CGP model?

Hi all,

I’m trying to reproduce Lu’s work for a further study, as in https://www.sciencedirect.com/science/article/pii/S0017931016333129. I set simulation parameters of CGPM-W27 according to the paper, but the output result cannot match the experiment as seen in the article, as can be seen in the attached figure,

while below is the article result, it very good agreement with experiment:

It’s the CGP parameters or Numerics parameters need change? Can anyone know?
I attach my mfx file below.
Thanks.

Are the material properties parameters in your DES settings correct? Have you verified whether the W8 case comparisons align with experiments or Lu’s work?

IMO it is unreasonable to expect better agreement than what you already show given all of the uncertainties in this experiment and model form.
