I am doing eigenfrequency analysis with periodic boundary conditions.

Even if I ask for 16 eigenfrequencies, in point evaluation I get 17 with 17th one as NaN. Why is that?

I tried everything from scratch again but had same issue. All other frequencies were correct and logical. My material is Polymer which I defined Isotropic and no damping.
