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.
: If your simulation diverges or throws an "out of memory" error, pasting the specific log output into the forum search bar usually yields a solution from someone who faced the same bottleneck.
: For users requiring more advanced algorithms, the forum discusses integrating external tools. As one Ansys employee explained, “Adding more advanced algorithms with faster convergence could be done through Python code and use Lumerical’s Python API.” They also recommended exploring optiSLang , another Ansys product compatible with Lumerical, for more sophisticated optimization workflows.

As GPUs become increasingly central to simulation workflows, the forum has seen discussions comparing CPU and GPU performance. A thread from January 2026 examined potential meshing differences between GPU and CPU simulations. While the grating coupler example showed identical grid points across both, users reported inconsistent behaviors that seemed to depend on machine history and Python-generated project file states.
The most popular topics from the old Lumerical Knowledge Exchange (>10,000 topics) have been migrated to the new forum. This includes years of solved problems, example scripts, and workaround methods for complex photonics problems. 3. Ansys Innovation Courses
