I saw in your reference :
Structure non-linearity can be related to a single structure element (structural or material non-linearity) or can be a result of the force-deformation relationship in the whole structure (geometric non-linearity).
but can't find any option to define nonlinearities!!!. Is there any option?
I want to define nonlinear concrete. Could you please help me? Thank you.
