Lumerical uses proprietary sub-pixel smoothing to accurately resolve curved material interfaces without requiring an ultra-fine, slow grid mesh.

In the realm of nanophotonics, computational electrodynamics is no longer a luxury—it is a necessity. Whether you are designing a silicon waveguide, a plasmonic antenna, or a metasurface, solving Maxwell's equations analytically is impossible for complex geometries. lumerical fdtd tutorial

Never trust your first simulation script explicitly. Run convergence tests by systematically tightening parameters until your results stop changing:

The panel allows you to:

: When performing convergence tests, avoid changing the override region size across simulations. Additionally, ensure that sources (especially dipoles) are located at consistent Yee cell positions corresponding to their polarization direction across all mesh resolutions.
