Hello,
I am modeling a very simple 2D unit cell in structural mechanics, which is only under mechanical point load. the study works well in stationary when I use linear elastic material model. But actually the material is rubber and it is hyperelastic, when I use hyperelastic model (Mooney-rivlin 2 parameters model) for my material the study doesn't work and gives me this error message.
Failed to find a solution. Maximum number of Newton iterations reached. Returned solution is not converged. Not all parameter steps returned.
Could any one help me with this error?

I forgot to mention that the model is a composite. The matrix is hyperelastic and the particles are linear elastic materials.
