Frequently asked questions
How does Ventorah work?
You upload a 3D model (STL, OBJ, STEP, IGES, GLB, FBX), configure flow conditions, and the solver runs in the browser using a parallel OpenFOAM backend. Results are displayed in real time with streamlines, pressure fields, and aerodynamic coefficients.
What file formats are supported?
STL, OBJ, STEP, IGES, GLB, and FBX. Models are rendered instantly in the WebGL viewer.
How accurate is the solver?
The solver is benchmarked against published wind-tunnel data. For example, sphere drag is within ~10% of experimental data.
Is there a free plan?
Yes, every account starts with 5 free demo simulations. No credit card required.
Can I export results?
Yes, you can export coefficients, charts, and flow fields as CSV or a PDF report.
What does the AI assistant do?
You can ask why drag is high or how to add lift. The assistant provides flow-separation explanations and design recommendations.
