Particle-based Fluid Dynamics Simulation

What is nanoFluidX®?

nanoFluidX is a particle-based hydrodynamics (SPH) simulation tool to predict fluid flow around complex geometries while in complicated motion. It is used for a variety of applications such as simulating oiling within conventional high-performance or electric vehicle powertrain systems comprising rotating gears, analyzing forces on individual components of the system or water management (wading, sloshing…).

It enables engineers to optimize efficiency by reducing friction or heat losses, improve reliability and safety, while limiting mechanical stress and hot points, or reduce fatigue.

Optimized for use on clusters of Graphical Processing Units (GPUs), it is extremely fast. For typical gear-train applications, without the need to simplify geometries, simulations can run an order of magnitude faster than a Finite-Volume code.

Key Features

Simplified Pre-processing

No need for mesh in a classic sense. Import the geometry, select the element, and generate the particles. No more hours of pre-processing and devising a good-enough mesh.

No Graphic

General Free-surface Flows

Simulate sloshing of oil in powertrain systems, free flowing fluids in an open environment, open or closed tanks under high accelerations and similar phenomena.

No Graphic

High-density Ratio Multiphase Flows

The Smoothed Particle Hydrodynamics (SPH) method of nanoFluidX enables easy treatment of high-density ratio multiphase flows (e.g. water-air) without additional computational effort.

No Graphic

Tank Sloshing

Accurate measurement of the forces experienced by the tank or vehicle during drastic acceleration, like braking or sudden lane change, by tank sloshing simulation.

No Graphic

Rotating Motion

nanoFluidX has implemented options for prescribing different types of motion, therefore simulating rotating gears, crankshafts and connecting rods in powertrain applications comes easy.

No Graphic

Rigid Body Motion

Besides rotational motion, the nanoFluidX code allows for element trajectories prescribed by an input file. Study the interaction of an arbitrary translationally moving solid and the surrounding fluid.
