Dear Ansys support team,

Where can I find a documentation of how nonlinear interactions (i.e., governing equation of motions, etc) are implemented in FDTD Lumerical? I would like to know, for example, governing equations of motions. To provide context, I am currently simulating a upconversion device, where propagating fields of two separate frequencies are incident on a nonlinear medium. Any help would be appreciated. Thank you!

Best,
