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)
    1. Go to Resources button in the toolbar.
    2. Look at Memory requirements. If it is too high, reduce the mesh accuracy in the FDTD Region settings or reduce simulation volume.

    Run Mode:

    The software discretizes the space into a "Yee mesh" and solves Maxwell's equations over time.
