Simulate material with X^2 off diagonal elements different from zero?

    • Albi.Pani

      Hi, I want to simulate a material whose nonlinear susceptibility tensor  contains only off-diagonal components.

      But when I try to add new X^2 material this has only one value or three for the diagonal case.

      What can I do?

      non-diagonal tensor must be diagnolized and use both the diagonal elements and the transfer matrix as input. please refer to this article and example
