Navier AI: Real-Time CFD Simulations
Navier AI Corp · Coding
Navier AI pairs an AI engineering agent with CFD and structural solvers, so you can set up, run, and review simulations in one workspace instead of five tools.
About Navier AI: Real-Time CFD Simulations
What Is Navier AI
Navier AI is a San Francisco company that builds CFD simulation software for hardware teams. Its main product is Prism, a desktop app that puts an engineering agent, a code editor, a 3D viewport, and a local solver runtime in one window. The same account also opens a hosted CFD workspace in a browser, which is the lighter way in if you don't want to install anything yet.
The pitch is the setup work it removes. Computational fluid dynamics normally means a CAD export, a meshing tool, a case directory, a terminal, and a separate post-processor. In Prism you describe the task and watch an AI engineering agent do it. The agent writes the case files, starts the solver, and shows you what changed. Ferro, Navier's own structural solver, ships inside the app. OpenFOAM, SU2, CalculiX, code_aster, and Project Chrono run as containers that the app installs for you.
Three limits matter before you commit. It costs $500 per seat per month, and there's no working free tier right now, since Navier has paused agent access on new free organizations. macOS builds are Apple Silicon only, so an Intel Mac is out. And the open source solvers need Docker on the same machine, which adds a second install and some container overhead.
Getting Started
- Ask Navier for a download link for your organization, then install the .dmg, .msi, or .tar.gz from releases.navier.ai.
- Accept the licence and sign in through your browser. Prism keeps the window locked until the account is active.
- Pick the folder you want the agent to work in. File access stops at that folder, so choose a project root rather than your whole drive.
- Work through the local tools screen. Docker is the one to tick if you plan to run OpenFOAM or another open source solver. Gmsh, LibreOffice, Typst, and the language servers are optional.
- Describe the job in a new thread, review the diff as the agent writes files, then ask for a report with the figures embedded.

Key features
An agent that sets up and runs the case
The agent has file, shell, search, browser, and solver tools, plus skills for specific engineering workflows. You describe the task in plain language and it authors the case, runs the solver, and reports back. Each turn is gated by a permission mode you choose, so you can keep it read-only until you trust it.
A CFD workspace you open in a browser
The web app is a hosted CFD workspace, separate from the desktop install. It suits a quick look at a case or a teammate who doesn't want to install software. Heavy runs still belong on your own hardware, since the desktop app is where the local solver runtime lives.
Solvers bundled and containerized
Ferro, Navier's structural FEM solver, is compiled into Prism with no licence server. OpenFOAM, SU2, CalculiX, code_aster, and Project Chrono install from inside the app and run as containers through navier-solverd. That mix covers fluid flow, structures, and multibody work in one place.
Code, CAD, and 3D results in one window
Prism opens STEP and STL geometry, a code editor, a terminal, and a 3D viewport side by side. You can read the case dictionary, look at the mesh, and check the pressure field without switching applications. For engineering simulation work, that cuts the usual alt-tab loop between five programs.
Long runs that survive a restart
Every step is saved as it happens. If a run outlives your laptop battery or the connection drops, the thread picks up where it stopped instead of starting over. Big jobs can also be split across sub-agents, which is how a batch of cases gets worked through in parallel.
Reports and run comparison
The agent can build a run-explorer dashboard over a folder of outputs, or produce a rendered document with figures embedded. Design-review decks with agenda and summary slides are part of the same skill set. You get an artifact you can hand to someone who wasn't in the session.
Pros and cons
Pros
- One seat covers the agent, CAD viewing, meshing, several solvers, and report output, so there's no stack of separate licences to reconcile.
- Cases, meshes, and results stay on local disk, and solves run on your own CPU, which matters when the geometry is under NDA.
- The durable harness means a dropped connection costs you a retry, not a lost night of solving.
- Usage is metered per organization, with token counts, call counts, and cost visible in settings, so a heavy week is not a surprise invoice.
Cons
- At $500 per seat per month, this is a team purchase. A solo hobbyist or a student has no realistic path in, and the paused free organizations close the usual trial route.
- OpenFOAM and the other open source solvers need Docker running on the same machine. That's a second install to maintain, and containers add overhead on large meshes.
- The macOS build is Apple Silicon only, so Intel Macs and older workstations can't run it at all.
- Permissive agent modes can write files freely, and stopping a turn is not an undo. You need git or a worktree habit before you let it run loose.
Frequently asked questions
It runs engineering simulations, mainly computational fluid dynamics and structural analysis, with an AI agent handling the case setup and the solver run. Teams use it for aerodynamics, thermal work, stress checks, and design comparisons.
