Uniaxial tension does not work in LS-Dyna ACT Workbench

      Hello everyone.
      I am calculating rubber in LS-Dyna ACT Workbench.

      If I use standard rubber from the database: Elastomer Ogden 3, then everything is solved. If I use my rubber, with uniaxial tension (I have test data) and Ogden 1 then I get the following errors:

      For the test, I also tried to remove data from the standard Elastomer Ogden 3 except for uniaxial tension and added Ogden 1, there are also errors.

      Why? What should I do to make it work?

      Thanks.

      Hi, 

      How stiff is your tested material? Have you tested with tet elements? If so, can you post your results? 

      Cheers, Ram

        Sir, it's very hard 80 shore.
        Yes, I used tetras.


        I can't show the results because there aren't any, the calculation doesn't start. It gives errors.
