Ansys 2025 R2 uses AI tools to simplify simulation, support collaboration, and improve team productivity.
Physics-based AI for Intuitive Simulations
Ansys 2025 R2 launches Ansys Engineering Copilot, a virtual assistant that draws on Ansys’ technical knowledge. This tool provides AI-powered support within Ansys products and connects users to resources such as Ansys websites, articles, over 800 courses, and the global user forum. It features AnsysGPT, which integrates Microsoft Azure AI Foundry and OpenAI models, and allows users to create and track support cases.
“We’re pleased to collaborate with Ansys as they continue to develop and integrate innovative AI solutions for their customers,” said Nidhi Chappell, vice president, Azure AI Infrastructure at Microsoft. “Integrating Microsoft Azure AI Foundry with AnsysGPT allows engineers to quickly access critical information and take advantage of the deep engineering expertise from Ansys to enhance productivity and accelerate innovation.”
2025 R2 adds AI capabilities across the Ansys portfolio to create, validate, and optimize simulation – speeding model creation, reducing manual effort, and mitigating human error.
- Ansys Engineering Copilot is available in Ansys Mechanical, Ansys Discovery, Ansys Fluent, Ansys HFSS, Ansys Electronics Desktop (AEDT), Ansys Scade One, Ansys Speos, Ansys Maxwell, Ansys optiSLang, and Ansys Lumerical products, connecting engineers to engineering expertise with one click
- 17x faster results for radiation pattern calculations and phased array antenna beam steering simulations with HFSS – critical to applications like 5G/6G, radar sensors, and satellite communications
- Seven Ansys products feature built-in AI functionality called AI+ that make simulations easier, faster, and more accessible, including the new Ansys Missions AI+ ODTK tool for orbital accuracy
- Integrating optiSLang and the Ansys SimAI platform accelerates dataset creation and AI training
Maximize Results Through Improved Data Handling and Automation
The new release improves digital engineering by simplifying data handling and management tasks, which helps teams work together. Better data management supports usage of data across the product life cycle, as well as training AI models and creating synthetic data. Updates to model-based systems engineering (MBSE) allow teams to collaborate using a unified data source, supporting digital continuity and teamwork across disciplines.
Expanded Python compatibility enables engineers to automate tasks, manage data, and maintain consistent workflows. For example, Danfoss Drives uses Ansys simulation to validate complex motor control system designs. The simulations help industries improve performance, lower energy use, and maintain operation through precise analysis of drive technology.
“PyAnsys is critical to enabling custom workflow automation, integration, and scalability across our simulation environment,” said Michael Laursen, head of virtual design, test & optimization, Danfoss Drives. “The open ecosystem allows us to connect tools and leverage AI for an accelerated end-to-end workflow. Ansys technology helps our teams advance and maximize our digital design processes to keep pace with an ever-changing industry, all while reducing costs and speeding product development.”
- Over 40 Python libraries within the PyAnsys collection, featuring PySTK and PyChemkin, which offers a Python interface to Ansys solutions to automate workflows and drives higher productivity across applications
- Reduce cybersecurity risks by automating threat analysis and vulnerability management in the web-based, cooperative solution Ansys medini Cybersecurity SE
- Directly connect software, safety, and simulation in one solution with the SysML v2 web-based platform Ansys System Architecture Modeler (SAM) Enterprise, delivering a MBSE methodology
Using smart automation and data management supports collaborative work across an organization. Advanced computational tools help teams turn insights into actions and carry out tasks with accuracy.
Replicate Reality with Advanced Computation
Addressing complex design problems depends on advanced physics models and simulations that reflect real-world conditions. Ansys continues to update its technology to help users obtain faster results and support new directions in product development.
- Faster performance on large transient models with the new mixed solver in Ansys Mechanical, supporting analysis of thermal changes over time
- Eliminate manual setup and improve the speed, rendering, and usability of meshing complex, stacked electronics systems with the mesh flow in Mechanical
- Ansys Rocky and Ansys FreeFlow provide multiphysics capabilities, including thermal, fluid-structure, and electromagnetic coupling for simulations and performance optimization
- Ansys PowerX debugging tool reduces design time in semiconductor power devices by identifying parasitic issues, streamlining setup tasks, and enabling 2D meshing
To illustrate, Ampleon leverages simulation technology to design GaN and LDMOS solutions for 4G LTE, 5G NR infrastructure, as well as for industrial, scientific, medical, broadcast, navigation and safety radio applications.
“Designing RF power products is challenging when managing electromagnetic, thermal, and mechanical interactions effectively,” said Dr. Vittorio Cuoco, team lead of modeling and characterization group, Ampleon. “Ansys’ solutions offer precise simulations that tackle these challenges head-on, minimizing design risks and improving reliability. The results are immeasurable – higher performance, energy savings, and greater efficiency.”
This acceleration is further amplified by the flexibility of cloud-based simulation. By leveraging on-demand technologies, businesses can drive digital transformation with ease.
Drive Digital Change with Cloud-based Simulation
Other updates focus on expanding computation through cloud technology, high-performance computing, and GPU-optimized systems. These features help users run simulations quickly, allowing for design exploration. The release also adds web-based and on-demand tools, making it easier for engineers to access resources and manage workflows outside the desktop environment.
