  Hi,
  I want to have a very fine mesh at the interface between two different materials. However, this interface is not just a flat horizontal surface, it has a pyramidal shape (image below). Is there a way to do a fine mesh only at the interface between the silicon (red) and material on top without having to do a square mesh encompassing the whole width of the simulation region?

  Lumerical FDTD and most FDTD software are based on rectangular meshing :Ansys Insight: About override mesh in FDTD Solutions: its use and settings
  Therefore it cannot apply local finer mesh that is not aligned with the axes.
  If you want, please try DGTD, which is a Finite-Element based mesh, and can handle such local finer mesh properly. Introduction to DGTD - DGTD Solver Physics
