Add an FDTD simulation region. Set the boundary conditions to PML in all directions except the propagation axis if using symmetric boundaries.
Boundary conditions (PML, Periodic, Bloch), source types (Plane wave, Gaussian, Total-Field Scattered-Field), and monitors (Frequency-domain, Time-domain).
Ensuring your PML boundary layers do not intersect physical structures unexpectedly. Speeding Up Simulation Times lumerical fdtd tutorial pdf top
The official Ansys website is the primary source for accurate material.
Before trusting your data, you must perform a convergence analysis. Run the simulation with a coarse mesh. Record the transmission. Tighten the mesh size (increase mesh accuracy). Re-run and check if the transmission value stabilizes. Advanced Topics to Look For
The mode source injected light, but it scattered instantly. This happens if the source injection plane is placed too close to the edge of the FDTD region or if the waveguide cross-section changes abruptly right at the source plane.

Before running a massive broadband simulation, always open the "Material Explorer" in Lumerical. Ensure the analytical fit line matches your experimental data points over your entire source bandwidth.

The numerical implementation of FDTD involves discretizing the computational domain into a grid of cells. Each cell is assigned material properties, such as permittivity and permeability. The FDTD algorithm then updates the electric and magnetic fields at each cell using the finite-difference equations. The algorithm consists of two main steps:
