How it works
From a sentence to a solved case, in three steps.
01
Describe
Upload your STP geometry and describe the conditions in plain language. The agent parses it.
Air, 20 m/s over my turbine blade. Give me Cd and pressure map.
02
Solve
The agent picks the solver, builds the mesh, runs the case, and checks for convergence.
→ snappyHexMesh 1.2 M cells → simpleFoam → converged 1820 it.
03
Explore
Interactive 3D viewer, residual plots, force coefficients. Export VTK, CSV, ParaView state.
→ Cd = 0.347 → Cp_min = −1.82 → Export VTK / CSV
Features
Built for engineers who'd rather solve problems than read dictionaries.
Auto meshing
snappyHexMesh tuned per geometry — no dictionary editing.
Solver routing
simpleFoam, pimpleFoam, pisoFoam — chosen automatically per physics.
Physics checks
Conservation, convergence, mesh quality validated every run.
Real OpenFOAM
Same OpenFOAM v2412 used across industry and academia. No surrogate.
Parametric runs
Re-run cases with different velocities or BCs, compare side-by-side.
Self-host ready
Docker Compose and Kubernetes manifests for air-gapped environments.
Frequently asked questions
Do I need to know OpenFOAM to use this?
No. Describe your problem in plain language — the agent selects the solver, builds the mesh, sets boundary conditions, and runs the case. You only need a CAD file and the physical conditions (velocity, fluid, etc.).
What file formats can I upload?
Geometry must be uploaded as STP (STEP) format. Make sure the model is a clean, watertight solid — assemblies should be exported as a single STP file.
What types of simulation are supported?
Currently the platform supports incompressible flow — both internal (pipes, ducts, manifolds) and external (bluff bodies, airfoils, vehicles). Compressible, multiphase, and heat-transfer cases are on the roadmap but not yet available.
How accurate are the results?
The platform runs real OpenFOAM simulations — the same solver used across industry and academia. Accuracy depends on mesh quality and boundary conditions, both tuned automatically by the agent but reviewable and overridable by you.
How long does a typical case take?
It depends on case complexity and on your plan's compute allocation — higher-tier plans run on more CPU cores and finish faster. As a rough guide, simple external aerodynamics or pipe flow typically completes in 10–30 minutes on a standard plan.
How does pricing work?
Pricing has two parts: tokens (consumed by agent reasoning) and compute (consumed by the OpenFOAM solver). Different plans bundle different token allowances and compute tiers. New accounts receive free tokens to try the platform.
Is my geometry data kept private?
Yes. Cases are isolated per user — other users cannot access your files. For on-premise or air-gapped environments, the platform can be self-hosted via Docker Compose or Kubernetes.
