Defining the boundaries of your simulation workspace dictates both accuracy and computational time.

Always verify the RMS error of the material fit before running a simulation to avoid unphysical results. B. Simulation Region and Boundary Conditions

Used for free-space optics, metasurfaces, and thin-film stacks.

For structure building, pay attention to coordinate inputs to ensure precise geometry. For a blazed grating example, you might set polygon vertices at coordinates (0,0), (Λ,0), (Λ,h) to achieve the correct blaze angle. lumerical fdtd tutorial pdf

If your device geometry and source profile are symmetric, use Symmetric or Anti-Symmetric boundary conditions. This cuts your simulation volume—and run time—by a factor of 2 or 4.
