Lumerical Forum Online
The most active section. Topics range from mesh refinement strategies to multi-coefficient material models. Common threads include optimizing simulations for metal optics (e.g., silver/gold at visible wavelengths) and reducing simulation time for large-scale solar cells.

The Lumerical Forum is structured to cater to different physics solvers and applications. Understanding the layout will help you find answers faster:
It is not an exaggeration to say that hundreds of peer-reviewed papers have been directly enabled by the Lumerical Forum. For example, a 2022 Optics Express paper on topological photonic crystals explicitly thanked the forum in the acknowledgments for resolving a boundary condition issue. Similarly, a semiconductor foundry recently published a case study showing how a script shared on the forum reduced their Monte Carlo yield analysis from 12 hours to 45 minutes. The most active section
This area covers photonic integrated circuit (PIC) design. Users share compact model libraries (CMLs) and scripts for co-simulating electronics with photonics. A classic thread involves linking Lumerical’s INTERCONNECT with external EDA tools like Cadence or Synopsys.
