Dear Subscriber,

When using auto-mesh, the FDTD solver aims to maintain a specific number of cells per shortest wavelength within the simulation (based on the material). If you change the refractive index, the auto-mesh algorithm automatically recalculates the mesh.

You can explore other mesh settings available in the FDTD Solver. For details, see the Mesh settings tab section in the FDTD solver - Simulation Object  documentation. Additionally, you can incorporate a Mesh Override object in your simulations. Refer to Mesh override - Simulation Object for more information.

Please note that modifying mesh settings might reduce simulation accuracy. For best practices and guidelines, review the following resources:

1. Selecting the best mesh refinement option in the FDTD simulation object
2. Understanding Mesh Refinement and Conformal Mesh in FDTD
3. Convergence testing process for FDTD simulations

Best regards,
Kirill
