Problem with Materials

  I'm trying to make an RC structure or beam, but in the released ANSYS when I go to the Egineering Data and try to use Concrete 35-MPA the only properties that the ANSYS shows me is the density of the concrete. I also tryied to reinstal it several times.
  
  Does anyone know how to get it fixed ?
  
  Thank you

  In that middle window, you are showing a different material than Concrete.

  thak you, I found my mistake. The problem was that I was trying to use a material with the modal analysis, but my question would be now why I can't choose a material in the modal analyses?

  Modal analysis is a linear analysis, so only linear material properties and linear contact is allowed in the model. Geometric nonlinearity in the form of Large Deflection also has to be turned off to get a fully linear model.
