Is the INTERCONNECT able to simulate four-wave mixing/second harmonic generation

  I can't simulate second-harmonic generation with the SHG waveguide provided by INTERCONNECT, and I realize that it doesn't provide a nonlinear waveguide with chi3 parameter, is it possible to do FWM and SHG in INTERCONNECT?

  SHG is in the waveguide model: https://optics.ansys.com/hc/en-us/articles/13534783507219-SHG-Waveguide-SHG-WGD-INTERCONNECT-Element
