Simulate Flow Without Meshing
New fluid simulation that runs on your GPU: fast, meshless, and no cloud bill per run.
How it works
- 1
Import your STEP file
Drop a .step or .stp file. It is read and prepared for analysis right in your browser.
- 2
Pick the inlet and outlet
Click the faces where the fluid enters and leaves, set the inlet speed, and choose water or air.
- 3
Run and get results
Solve on your GPU and read the flow, the pressure drop, and the flow rate delivered, with a confidence check on every run.
No meshing
Your part becomes a signed distance field, split automatically into a grid of cells that handles complex curves and fine features without breaking. Run physics directly on your imported STEP file.
Validation of results
CFD is in beta. Each benchmark rebuilds the published problem and solves it on your GPU. In our runs, each landed within the band shown next to its reference.
