Fermi Physics

Abstract. Fermi helps thermal engineers move from messy CAD to useful simulation results in minutes, not days. The objective is to reduce time spent on simulation setup while preserving the engineering judgment required to choose useful studies and interpret results.

Keywords: thermal simulation, CAD cleanup, meshing, electronics cooling, design validation.

1. From messy CAD to thermal insight.

Fermi keeps the setup path short so engineers can spend more time testing assumptions and improving the design.

Figure 01. Submit geometry and automate cleanup. Start from enclosure CAD, a board layout, a thermal assembly, or an existing mesh. Fermi removes nonessential detail, identifies thermal regions, and prepares the model for simulation.

Figure 02. Set up the case. Reusable templates to handle materials, heat loads, fans, boundary conditions, and solver configuration.

Figure 03. Run and compare. Launch studies, compare design variants, and see whether a geometry change actually improves the thermal path.

Figure 04. Interpret the result. Get bottlenecks, likely causes, sensitivities, and recommended next checks instead of another raw plot dump.

2. Simulation setup is consuming the engineering day.

Engineers spend too much time moving between CAD, meshing tools, solver settings, scripts, screenshots, and status windows.

By the time the model finally runs, there is less time left for the part that matters: deciding what to simulate, what the results mean, and what to do next.

4. Fermi competes with the ways simulation gets avoided.

Default path	What it costs
External consultancies	Outsources the learning loop your engineering org should own.
Waiting to hire more specialists	Slows the team down while the talent pool remains limited.
Manual CAD-mesh-solver workflows	Burns senior engineering time on operational work instead of thermal reasoning.
Skipping simulation	Feels faster until failures, delayed launches, and expensive physical iteration arrive.

Fermi is the internal workflow layer for teams that want simulation to become a repeatable design habit.

Appendix A. Pilot intake

The recommended pilot starts with an NDA-gated use-case submission, optionally including geometry or assembly files. After the case is scoped, the team books a working session to define inputs, constraints, and success criteria.
