Mentioning your troubleshooting steps helps others understand where you’re stuck and prevents redundant suggestions. One user who resolved their DBR divergence issue shared that they had tried adjusting PML layers, mesh settings, and dt stability factors before seeking help. lumerical forum

Simulating light propagation in nanoscale structures. covering solvers like FDTD

[Product] + brief issue (e.g., [FDTD] Large E-field at monitor boundary ) lumerical forum

: Finite-Difference Time-Domain solver for sub-wavelength structures. MODE : Waveguide design and directional coupler simulation. CHARGE : Semiconductor charge transport modeling. HEAT : Thermal modeling for thermo-optic effects.

This is the heart of the Lumerical community, covering solvers like FDTD, MODE, CHARGE, DGTD, and FEEM.
