OpenFOAM v2406 · cfMesh · build123d / OCCT

CAD that ships with
its error bars.

Describe a part, get real B-rep geometry, then run CFD on the exact part you generated. Every result arrives with the mesh that produced it, the convergence behind it, and our measured error against published experiment.

What it does

01
Generative CAD

Describe a part in plain English. Get parametric B-rep geometry — STEP and STL — built on the same OCCT kernel your CAD package uses.

02
CFD on the part you generated

OpenFOAM v2406, cfMesh, k-ω SST. Not a proxy, not a render: the exact geometry, hashed at upload and re-verified before it is meshed.

03
Every number carries its evidence

Mesh recipe, cell count, y⁺, convergence, residuals, the reference area — and a diagnostic when a result is not defensible.

04
Published error bars

The solver is run against Hoerner, Schlichting and Achenbach, and the table is public — the misses included.

Run one part through it.

Generate geometry, mesh it, solve it, and read the evidence — in the browser.
