Why it mattersA hardware engineer often spends days on manual CAD and setup. If Prism works, that time moves to design choices instead of file handoffs.
Software agents can write code. Now they can design the hardware. Navier launched a desktop app on Tuesday called Prism. Describe the part or the study you need. Agents build the CAD model, run physics simulations, write scripts and hand back an engineering report.
Navier is a Y Combinator W24 company. It launched Prism on YC on 3 November. The app is a free download for Windows, macOS and Linux. The company's two cofounders are Cameron McCord and Evan Chermak. They previously worked on vehicle engineering at SpaceX, General Atomics, Aurora and Astranis.
What Prism does
Navier says a hardware design study often crosses half a dozen tools. CAD, meshers, solvers, scripts and slides. Every step is manual. Every handoff between tools is done by hand. A single study can take days, so teams pick a direction early and test a few variants.
Prism puts an agent across the whole chain. The company says you describe the work in plain language. One example is "design a cooling module for this drone" with a CSV of constraints. Another is "generate a Cl-Cd curve for this wing". The agent then builds the CAD, meshes it, runs the physics and writes the report.
Navier's own worked example is a drone cooling module. The agent built the CAD and ran CFD in OpenFOAM. It then ran a modal analysis in CalculiX, checked manufacturability and wrote a report. The report named a recommended design and the next steps. The company says agents can be split across a design space, so several variants are explored at once.
What is under the hood
Navier says Prism includes 13 physics solvers. The list includes OpenFOAM, SU2, CalculiX, Elmer, code_aster, Project Chrono and Yade. Navier also includes its own GPU-native FEA solver called Ferro. The app includes 3D viewers for STEP files and solver results, plus plugins for Onshape, GitHub and Atlassian.
Every script, assumption, mesh and solver input is a file in the project. Navier says engineers can check the work the way they would check a colleague's. Geometry and simulation files stay on the local machine.
What is new, and what is still unclear
An agent that writes CAD and runs a CFD study end to end is a new capability for hardware teams. The usual chain is a human moving files between CAD, meshing and solver tools. Each tool has its own setup. A tool that owns the whole chain removes the handoffs. It also owns every assumption behind the result.
Navier states the gain as time saved on busy work. It does not give a measured number. The YC launch does not name a customer or a count. The company's ask is for hardware engineers to download Prism and try it on a real problem. The founders want email about where it works and where it falls short. No review of real engineering results from users is public yet.
A team that already runs OpenFOAM or CalculiX by hand can start with a test. Pick a problem whose answer the team already knows. Compare the agent's mesh, boundary conditions and final numbers against a case the team has already run. If the agent's assumptions are wrong, the design it recommends is wrong, however fast it got there.
