Lumerical FDTD
(Finite-Difference Time-Domain) is the industry standard for modeling nanophotonic components, offering a high-performance 3D electromagnetic solver that solves Maxwell’s equations for complex geometries. This tutorial covers the end-to-end workflow, from initial setup to advanced performance optimization. 1. Standard Simulation Workflow
Part 5: Running the Simulation
Step 4: Adding Sources and Monitors
Boundary Conditions (BC)
- Go to Resources button in the toolbar.
- Look at Memory requirements. If it is too high, reduce the mesh accuracy in the FDTD Region settings or reduce simulation volume.
- Click on "Source" > "Point source" to create a point source.
- Set the position to (5 μm, 5 μm, 5 μm).
- Set the wavelength range to 400 nm - 800 nm.
Run Mode:
The software discretizes the space into a "Yee mesh" and solves Maxwell's equations over time.
