You'll need to use three equations. One for the third order and one
each for the real and imaginary parts (all coupled together).

You need to download an unreleased version of the code using
subversion. Unfortunately, the coupling functionality has not yet been
officially released yet. See

Using the coupling functionality should work well with this equation.
Good luck.
