Use a coarse global mesh (e.g., mesh accuracy 2 or 3) for initial prototyping, and save mesh accuracy 4+ or tight overrides for final verification. Early Shutoff: Set the autoshutoff min threshold to 10-510 to the negative 5 power 10-610 to the negative 6 power

FDTD uses a discrete Yee cell grid. A good PDF will teach you: How to use to save simulation time.

Lumerical FDTD is a commercial software package developed by Lumerical Solutions, Inc. It is used to simulate and analyze electromagnetic phenomena in various fields, including photonics, optics, and electromagnetics. The software uses the finite-difference time-domain (FDTD) method to solve Maxwell's equations, which describe the behavior of electromagnetic waves.

Use Frequency-Domain Field and Power monitors for spectral data, and Time-Domain monitors to debug pulse propagation.
