PITTSBURGH, PA, Apr 10, 2025 – Ansys and NVIDIA unveiled a new technology framework enabling customers to design tailored solutions using the power of AI, advanced simulation, and physically-based visualization. Converging Ansys and NVIDIA open-source technologies narrows the gap between simulation and reality by enabling customized workflows, fostering collaboration, and making simulation more accessible to non-experts. Ansys applied this framework to demonstrate how it can empower clinicians to analyze human heart anatomies in extreme detail, equipping them with deeper insights to make informed decisions.
PyAnsys is a set of open-source Python libraries that connect Ansys tools with Python, allowing users to run simulations, modify geometries, and process results through scripted workflows. NVIDIA NIM — a set of inference microservices for developers to deploy AI models — enables Ansys users to connect with large language models (LLMs), in this case, via a chatbot. Prompting the chatbot with specific queries about the model triggers the LLM, trained with selected PyAnsys libraries, to auto-generate customized PyAnsys code. This ultimately enables high-fidelity simulation and visualization within applications built on NVIDIA Omniverse, allowing non-experts to forgo learning the underlying complex system of tools needed for simulation.
Customers across industries can benefit from this technology. Users can use Python to modify existing models and train an LLM for specific tasks. Non-specialists can access simulation results through a customized or chat-based user interface.
The demonstration at GTC showed how the framework can enable tailored treatments and outcome predictions for those with cardiovascular disease — the leading cause of death in the world. From within the “PyAnsys-Heart” library, a clinician can ask the chatbot, “What does my patient’s heart look like?” “PyAnsys-Heart” will generate code for that specific patient’s heart, enabling a partial or complete anatomical model in LS-DYNA. The model can then be visualized in an application developed with Omniverse for visualization, unlocking insights that could have otherwise been inaccessible.
“As a surgeon, we have plenty of expertise in dealing with the common cases,” said Dr. Francis Bessiere, cardiac electrophysiologist at Louis-Pradel Cardiovascular and Pulmonary Hospital. “However, the exciting promise of combining computational technologies like simulation, visualization, and AI becomes clear when we can predict which cases will be challenging and prepare the health system to optimally care for the more complex patient cases.”
This collaboration also sets the foundation for Ansys and NVIDIA to jointly leverage new tools and workflows for creating high-fidelity, multi-modality, multi-scale physics and physiological simulation for use with NVIDIA Isaac for Healthcare.
“Ansys is committed to helping its customers innovate, and that means enabling rapid testing and deeper insights to instill confidence in product performance,” said Prith Banerjee, chief technology officer at Ansys. “It also means that simulation should be accessible by more than a few specialists within an organization. Ansys and NVIDIA recognize this, and our open ecosystem approach to digital engineering and product development sets the standard for collaboration, and as evidenced by our demonstration, has transformative potential for cardiac care and beyond.”
“The collaboration with Ansys is foundational to accelerating the next generation of medical imaging and robotics,” said Rev Lebaredian, vice president of Omniverse and simulation technology at NVIDIA. “The power of advanced GPU computing, physical AI, and simulation will shape the future of personalized healthcare.”
