The Evolution of Simulation Workflows
What if understanding a simulation no longer depended on sifting through layers of models and results, but on simply asking the right question?
Virtual Companions and Generative Experiences introduce new ways to interact with simulation and engineering knowledge on the 3DEXPERIENCE platform. Together with the latest simulation technologies introduced in 3DEXPERIENCE SIMULIA R2026x FD03, they reflect the continued evolution of engineering workflows.
In the sections that follow, we explore both the platform capabilities that extend how engineers work with simulation and the latest R2026x FD03 innovations across the SIMULIA portfolio.
Virtual Companions Support Simulation Workflows
Simulation workflows often require users to configure analyses, validate models, manage simulation data, and interpret results across increasingly complex products.
Virtual Companions are the AI-powered virtual workforce of the 3DEXPERIENCE platform. Each Virtual Companion has a specific mission, accomplished through Competencies, and a distinct personality.
Competencies represent the ability, to perform a particular job or purpose. A Competency covers an entire domain of expertise, relying on more granular skills.
For simulation workflows, LEO assists users by helping them explore project information, validate simulation scenarios, visualize models, and examine simulation results through natural language prompts. By combining enterprise knowledge with engineering context, Virtual Companions simplify access to relevant information while reducing the effort required to perform routine tasks.
LEO Brings Natural Language Interaction to Simulation
Among the three Virtual Companions currently available on the 3DEXPERIENCE platform, LEO is the engineer, designed to support engineering activities through natural language interaction. For SIMULIA users, LEO helps set up simulations using your company’s best practices and knowledge.
LEO supports simulation workflows by helping users:
- Generate design performance insights and physics KPIs through natural-language interaction.
- Set up, run and analyze simulation results with confidence, regardless of prior simulation experience.
- Summarize project objectives, model components and simulation-specific data on request.
- Control visualization with a simple prompt—no manual menu navigation.
- Explore and process results automatically with a single typed request.
- Automate simulation setup and analysis for real industry test cases, saving considerable time.
