Key Feature 1 – HFSS GPU Acceleration Using cuDSS [Beta]
What's new: HFSS now supports GPU acceleration using cuDSS, including:
• Frequency sweeps acceleration when the "Save Fields" option is enabled, and
• Multi-node distribution support

Advantages:
• When "save fields" is enabled in frequency sweep setup, multiple frequencies can be run in parallel,
providing a significant speedup over running frequencies in serial
• Larger models and/or more frequency points can run now that simulations are not restricted to the RAM
available on a single GPU
