We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Hello,

I can’t speak for COMSOL.

For Lumerical, some general recommendations can be found in the article Hardware specifications guidelines – Ansys Optics. While having more RAM is beneficial, FDTD simulations are typically limited by memory bandwidth because they involve constant, large-scale data movement between the CPU and RAM. Therefore, in addition to RAM size and the number of cores, prioritize multi-channel memory architectures with faster RAM.

Additionally, Lumerical now supports GPU acceleration. For more details, please see Getting started with running FDTD on GPU – Ansys Optics.

Best regards,
Kirill
