Every run reviewed by a CFD engineer
CFD for sails, hulls and foils, without the CFD learning curve.
Upload your geometry, set the sailing conditions and get forces, moments and pressure maps you can trust. The simulation runs in the cloud, and an expert checks it before it reaches you.
Easy
Ask a sailing question, not a meshing question.
You describe the boat and the conditions in the terms you already use: wind speed, wind angle, heel, leeway. Kuma turns that into a simulation. No meshing, no solver settings, no hardware.
Reliable
Automated where it should be. Human where it matters.
Software does the heavy lifting, and a CFD engineer checks every job. You get the speed of a cloud tool with the confidence of a consultancy.
How it works
From CAD file to validated forces in four steps.
Upload your geometry
Hull, appendages, sails, wings or foils, straight from your CAD files.
Set the conditions
True wind speed and angle, heel, trim, leeway and sinkage. Sweep any of them to compare variations in one task.
An engineer checks the run
A CFD expert reviews the geometry, mesh and solver set-up, and signs off convergence before you see a number.
Read the results
Forces and moments in lab, boat or CAD frames, pressure maps on the 3D model, and side-by-side comparison.
Results
Numbers you can act on, and the picture behind them.
Forces and moments, three frames
Read every component in the lab, boat or CAD frame, with totals and per-part breakdown.
Sweeps built in
Give course wind angle, true wind speed or leeway several values and compare them in one task.
Isolate any part
Select a wing, crew or appendage to see its share of the load in the 3D view.
Convergence in plain sight
Every job shows its convergence history, so you can see the result settled.
Experts in the loop
A CFD engineer on every job.
Easy tools can give confident wrong answers. Kuma does not hand you a result until someone who does this for a living has looked at it.
- Geometry checked for gaps and bad surfaces before meshing
- Mesh and solver set-up chosen for your case, not a generic template
- Convergence reviewed and signed off on every job
- A real person to ask when a result surprises you
“The complex tasks CFD runs are always reviewed to optimize the reliability of the numerical results.”
Applications
Built for marine flows, above and below the water line.
Sails
Upwind and downwind sails, with pressure and forces across the sail plan.
Wings & kites
Wing foils, kites and rigid wings in true wind with gradient and shear.
Hulls & appendages
Resistance, side force and trim for hulls, keels and rudders.
Hydrofoils
Lift, drag and moments on foils, masts and fuselages.
