Macadamia

AI Copilot for Mechanical Engineers

We’re building autonomous AI agents that take over the role of engineers in running simulations with advanced physics-based solvers, like Ansys. Engineers submit their CAD designs and simulation requests, and Oswald automates the entire process - from model setup to interpreting results. It’s integrated with Ansys, the industry leader in engineering simulations.

What is the core problem you are solving? Why is this a big problem? What made you decide to work on it?

Physics-based simulations are critical for engineers to predict how designs will perform under real-world conditions. However, tools like Ansys, while powerful solvers, demand extensive expertise and time-consuming workflows.

What is your long-term vision? If you truly succeed, what will be different about the world?

A world where human engineers work together with AI engineers. A world where anyone can design and develop advanced hardware.
