Online Training Course

Fundamentals of AI for Simulation Engineers

17 - 20 March 2025 | Online | 4 hours each day

8:30am (Los Angeles) | 11:30am (New York)
4:30pm (London) | 5:30pm (Berlin)

Course language: English

This training course is designed to equip simulation engineers with a good understanding and practical skills in applying Artificial Intelligence (AI) in their field.

It is designed to be software-agnostic, prioritizing methodologies, and techniques that engineers can apply across various computational platforms.

The course consists of two parts:

The first part is an interactive lecture, which introduces the theory and mathematical background behind artificial intelligence.

The second part of the course are hands-on exercises, where participants will learn how to create their own Deep Learning models.

T​rainer

M​ax Kassera (yasAI)
Max Kassera studied mechanical engineering with a minor in economics at the University of Kaiserslautern-Landau, where he first applied machine learning and artificial intelligence to turbocharger design in 2017. After graduating, he was awarded two German government grants to develop AI software for mechanical engineering, which led to the incorporation of yasAI in 2022. With yasAI, Max began training engineers in applying AI to simulation projects with a focus on simulations and fluid mechanics.
