Why clients call

A wrong design costs more than a simulation.

Every design–build–fix loop burns weeks and a lot of money. A good simulation shows you what will happen, and why, before you commit.

“If the reservoir is released or the dam fails, where does the water go and when?”

→ 3-D free surface on real terrain: arrival time, water level, affected zones, compared with laboratory dam breaks.

“How hard does the wind hit this tower, and where does the stack plume go?”

→ Wind loads and dispersion on tens of millions of cells, running in minutes on one GPU.

“What is the drag of this design: a rider, a wing, a machine?”

→ Drag and lift for complex shapes and moving parts.

Validation

Against experiments, exact solutions and published benchmarks.

Every case states what it was compared with and how large the error is, with the figures and video.

What we simulate

The hard physics that push-button tools skip.

Free surface & dam break

Dam break, reservoir release, waves, sloshing, flooding over real terrain.

Wind loads & dispersion

Tall buildings, stacks, industrial sites, turbulent atmospheric wind.

Aerodynamics of complex shapes

Riders, wings, machines: STL geometry voxelised directly, no mesh generation.

Moving bodies

Pedalling legs, flapping wings, rotors: prescribed motion with forces over time.

Large scale on one GPU

Hundreds of millions of cells on one card with FP16 storage and adaptive refinement.

Custom solver & training

We add the physics you need to the solver and train your team to re-run it.

How it works

Clear from day one. No surprises.

You know the scope, price and deadline up front, and you see progress all the way.

Free feasibility review

You describe the problem. We tell you if simulation can answer it, how, and with what accuracy.

FAQ

Before you ask.

Is a lattice Boltzmann solver accurate?

Accuracy comes from the model, the grid and the validation. The Validation page shows every case against experiments, exact solutions or published benchmarks, including where we are not yet within tolerance.

What can QuanFlow not do yet?

External aerodynamics at very high Reynolds number (for example the Ahmed body) and rotating propellers are not yet within tolerance, so we do not offer them. If your problem is of that kind we say so and propose another tool.

Is my geometry and data kept confidential?

Yes. We sign an NDA before receiving any file. Client projects are never published without written permission.

What do I need to provide?

A short description and the question you need answered. Later: CAD (STEP/STL), operating conditions and measured data if you have it.

How much and how long?

Every study gets a fixed price after the free review. Review in 24 h; a standard study takes 1–6 weeks.
