Integrating for optoelectronic devices and HEAT for thermal management in waveguide structures. Conclusion

Since the acquisition, the forum has become more integrated with the broader Ansys ecosystem (including HFSS, Q3D Extractor, and Mechanical). Recent updates include a unified login with the Ansys Customer Portal and better support for multiphysics coupling. Expect to see deeper AI-assisted search within the forum—allowing you to ask natural language questions like, “How do I model a graphene-based modulator in FDTD?” and receive curated threads as answers. lumerical forum

Any idea what's causing this? Could it be a resonance artifact or boundary reflection? PML layers are 8 layers with 'standard' profile. Integrating for optoelectronic devices and HEAT for thermal

I have set up a 2D simulation of a ring resonator. I defined the silicon core with a mesh override region to resolve the 1550nm wavelength properly. However, after roughly 20% of the simulation time, the job manager reports: "WARNING: Electric field values are too large... simulation diverging." Expect to see deeper AI-assisted search within the
