About
With over 11 years of experience in computational engineering, I specialize in the unique intersection of mechanical simulation, software development, and artificial intelligence. My journey began with a foundation in mechanical engineering and evolved into developing sophisticated simulation tools and AI systems that solve complex engineering challenges.
At Wölfel Engineering, I've pioneered the development of Casimir/Automotive, a comprehensive Python/TCL scripting framework that integrates with industry-leading tools like Abaqus, LS-Dyna, and HyperWorks. My work spans from finite element analysis and seating comfort engineering to cutting-edge AI development, including the Casimir AI Assistant—an agentic AI system with RAG capabilities that runs efficiently on just 6GB VRAM.
I'm passionate about bridging the gap between traditional engineering disciplines and modern AI technologies, creating tools that enhance productivity and unlock new possibilities in computational engineering. My diverse background enables me to approach problems from multiple perspectives, whether it's optimizing wind turbine simulations or fine-tuning large language models for specialized engineering applications.
