Sim4Life V9.4 was released on March 5, further strengthening its position as the platform of choice for neurostimulation modeling, with targeted improvements to quality, robustness, and usability driven by demanding real-world application work. Key highlights of the new release include: Thermal unstructured stationary solver: New solver enabling the calculation of steady-state temperature distribution in complex geometries using an unstructured mesh. NVIDIA Blackwell GPU support: Added support for NVIDIA Blackwell architecture GPUs, ensuring compatibility with NVIDIA’s next-generation GPU hardware. Improved alignment between GUI and Python workflows , a clearer API structure, and more accessible documentation support large-scale, script-driven studies. Rebuilt manual and Python API reference for an improved browsing experience and search functionality. Stability, performance, and quality assurance: Improved robustness and performance for complex, large-scale models Cleaner, more consistent user interface (Web version) to improve focus during modeling and simulation setups. Integrated AI assistant (Web version): Accessible directly from the search bar to answer questions about tools, workflows, solvers, and APIs. Sim4Life V9.4 Web is available on all our cloud platforms for commercial users, researchers, and students. Sim4Life V9.4 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. We thank you for your valuable feedback and hope this release further enhances your productivity and workflows.

When the stop button is pushed in the task manager, while a simulation is running, it will generate an event that is equivalent to "enforcing" a "convergence reached" state from the solver perspective. That's why the following log will appear inside the Solver-Log tab WARNING: [...] Simulation end request received. The solvers starts to consider this. Steady state detected at iteration x, remaining time steps are y. Simulation performed z iterations. Elapsed time for 'Time Update' was xx:xx:xx wall clock time.

Hello, I was following the Tutorial: F.Temporal Interference Stimulation with Ohmic Electro Quasi-Static Solver with a Personalized Head Model Here I've noticed for the 'Grid' settings: The bounding box (or wire block?) for the head was used for manual gridding with 0.7 mm resolution Automatic Grid settings were set for the 4 TI electrodes I had some questions in regard to this setup. When I do not add the Automatic Grid settings for the 4 TI electrodes (so just one manual grid for the bounding box), the interfering E-field results change. I am confused why there is a change, as the bounding box still encompasses the head model and the electrodes. Why not just include the entire head model instead of the bounding box? Would it not be more accurate to automatically grid the segmented surfaces of the head model? Comparing the results for the different grid settings was done in the same manner by: Overall Field - Normalize Frequency Domain Results (0.001 A) - Multiplier (EM x2) - Mask Filter to ROI - Max Modulation Thank you for your time and help!
