The solver you can read.

OxiPhys is open-source finite element and finite volume software: a Rust core, a Python interface and a desktop app, for static, modal, buckling, thermal and flow analyses, from the sketch to the result.

Try what it does, right here.

Each card runs a small model in the page: drag, hover or type. The app does the same work on real geometry, with real meshes.

001DRAG

Static structural

Pull the beam’s free end. The load and deflection follow beam theory for a 1 m steel bar, 50 by 50 mm.

002HOVER

Modal and buckling

Move across to pick a mode. The frequency ratios are the exact ones for a clamped beam: 1, 6.27 and 17.55.

003HOVER

Thermal

Your pointer is a heat source on a plate with cool edges. Watch the heat conduct away.

004DRAG

CFD and OxiTunnel

Drag the cylinder through the stream. This card draws ideal flow; the app solves the full equations.

005HOVER

Meshing

Move across to change the element size. Round extrusions get hexahedra swept from a profile like this one.

006HOVER

Engineering drawings

ISO sheets with sections, dimensions and detail views. Move the detail circle over the part.

007DRAG

Part design in 3D

Sketch, extrude, fillet and turn the part freely. Flick it: it keeps spinning, then settles.

008TYPE

Seven steps, in the order you work.
