  Which Lumerical solver is best for 2D simulations, please?
  Should I use 3D FDTD or 2.5D Variational FDTD?
  Thank you!

  FDTD has a 2D FDTD solver:
  This would be the best choice for simulations of periodic 2D structures, for example: https://support.lumerical.com/hc/en-us/articles/360042089353
