Lumerical Forum Jun 2026

: Driving Lumerical simulations from Jupyter Notebooks or external IDEs.

Lumerical's true power lies in automation via the Lumerical Script Language (LSF) and the Python API (lumapi). The forum is an extensive repository for custom scripts. Users regularly share code for:

If possible, upload a simplified version of your .fsp or .lms file, or paste the problematic snippet of your Lumerical script. Connecting with the Broader Lumerical Ecosystem

Post a screenshot of your layout and the transmission spectrum if possible.

Does anyone have suggestions on how to stabilize this simulation? Any advice would be appreciated.
