The Intersection of AI and Simulation Technology

Since the mid-20th century, scientists and engineers have tested, validated, and improved their designs with the help of simulation. With every model, simulation software generated synthetic data — millions of calculations about what works and what doesn’t. Today, artificial intelligence (AI) is combining these learnings with real-time insights to fill in the gaps of what’s possible, making simulation faster and more accessible than ever before. 

What are the Benefits of Combining AI and Simulation?

How Training AI Enables Fast Predictions

For AI to work, it needs to be smart. Data simulation is widely used to train AI across topics.

Simulation data is pulled from past simulations and fed into the AI system based on the area of interest. For example, if the AI is learning about integrated circuits, the user would load performance results of circuit boards into the software.

Generative AI applied to 3D physics leverages previously generated simulation results from physics-based solvers to train the AI models and deliver faster predictions. An important advancement of data-driven approaches compared to existing reduced-order modeling (ROM) approaches is that engineers don’t need to parametrize their geometries to build the AI model. As a result, the performance predictions can be done across design changes, even when the geometry structure is inconsistent.

During the simulation process, design variants of a geometry are fed to the AI, and prediction of physics performance are almost instantaneous. This makes design iteration, exploration, and optimization much more efficient and accessible to a wider engineering audience, such as designers, system engineers, and methods and tools specialists.

Traditional physics-based solving methods can also be used to validate selected best designs with full fidelity simulation.

The Future of AI and Simulation

The mutually beneficial relationship between AI and simulation will continue to increase efficiency for engineers and designers. As the two technologies become more prolific across industries and applications, their broad adoption beyond engineering will further accelerate human advancement. As more people unlock the power of prediction by combining these powerful tools, the possibilities will expand exponentially.

An example of the combination of AI and simulation is a recent addition to the Ansys product family. Ansys SimAI is a machine learning platform for engineers who want to rapidly explore and predict the performance of new concepts across design phases. SimAI provides reliable and fast results and is accessible through a user-friendly cloud-native application.
