#### Topic: Automatic generation of concrete parameters

Hi,

The ATENA theory manual gives a table with formulas used for automatic generation of concrete constitutive model parameters for the SBETA model. In my case, I am using the Cementicious2 model in GiD (CC3DNonLinCementitious2). Are these formulas still applicable? In particular, I am looking at the formulas for Initial Elastic Modulus and Fracture Energy. When using the formulas specified, I am not getting the same values as the automatically generated ones. Can you please clarify? Also, what is the Initial Elastic modulus formula based on?

I am using GiD 11.0.8 and ATENA 5.3.2 Build 12360

Thanks
