The OpenSees Community

Hi, I´m trying to recreate an OpenSees example where the concrete materials Concrete01, Concrete02, Concrete03, Concrete04 are compared. I'm using the same data but I can´t get the same curve for the Concrete04. This is the example that I found on OpenSees: http://opensees.berkeley.edu/OpenSees/manu...

I am also having the same problem. Does anybody knows what should I do?

Thanks
