Sim4Life V9.6 removes a long-standing computational bottleneck in neurostimulation modeling and delivers platform refinements that make the resulting workflows faster and more intuitive. Key highlights include:

• Faster Neural Response Prediction: Generalized Activating Function (GAF) now supports clinically realistic MRG double-cable axon models, delivering near-NEURON accuracy while reducing computation times from hours/days to seconds/minutes.
• Automated Recruitment Curve Analysis: New integrated tools generate and compare recruitment curves across heterogeneous nerve populations, accelerating neurostimulation device evaluation and treatment planning.
• Enhanced Performance & Scalability: Faster project startup, improved handling of large anatomical/neural models, and support for NVIDIA Blackwell cloud GPUs for demanding optimization workloads.
• Improved User Experience & Automation: Modernized Python scripting environment and improved feedback during project loading and initialization.

Sim4Life V9.6 Web is available on all our cloud platforms for commercial users, researchers, and students.

Sim4Life V9.6 Desktop is available directly through the Automatic Software Update window in the Sim4Life GUI. Your current license file provided by ZMT remains valid for this version.

A detailed list of all changes can be found in the Release History.
