What is nanoFluidX?
nanoFluidX is a particle-based fluid dynamics solution tool to predict the flow in complex geometries with complex motion. It can be used to predict e.g. the oiling in powertrain systems with rotating gears or shafts and analyze forces and torques on individual components of the system or predict the sloshing in tanks with transient motions. Applying GPU-based technology empowers high performance simulations of real geometries.
Key features & benefits of nanoFluidX
The particle-based nature of the nanoFluidX code allows for an elegant and efficient approach to flows which undergo high deformation during the simulation.
- General free-surface flows
- Simulate sloshing of oil in the powertrain systems, free flowing fluids in an open environment, open or closed tanks under high accelerations and similar phenomena.
- High-density ratio multiphase flows
- The Smooth Particle Hydrodynamics (SPH) method of nanoFluidX allows for easy treatment of high-density ratio multiphase flows (e.g. water-air) without additional computational effort.
- Rotating gears, crankshafts and connecting rods
- nanoFluidX has implemented options for prescribing different types of motion, therefore simulating rotating gears, crankshafts and connecting rods comes easy.
- Tank sloshing
- Measure forces experienced by the tank or a vehicle during drastic acceleration, e.g. braking or sudden lane change.
- GPU computing
- FluiDyna GmbH is an Nvidia Preferred Solution Provider, allowing the nanoFluidX team a competitive edge in terms of code optimization and performance. GPU computing provides a significant performance advantage and power savings with respect to their more cumbersome CPU counterparts.
- Simplified pre-processing
- Mesh in a classic sense is not needed. Import the geometry, select the element and generate the particles. No more hours of pre-processing and devising a good-enough mesh.
- Rigid body motion
- Besides the 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.
