Altair nanoFluidX
Fluid dynamics simulation based on particle flow
Altair nanoFluidX is a fluid dynamics (SPH) simulation tool for predicting flows in complex geometries with complex motion. It can be used to predict lubrication in drive systems with rotating shaft / gears and to analyze force and torque on individual components of the system. The use of GPU technology enables high-performance simulation of real geometry.
1. Benefits of the nanoFluidX software
Altair nanoFluidX is based on the SPH formula, which contains a number of exclusive features that improve the accuracy and turn nanoFluidX's source code into the only particle-line-based solution on the market.
The software is created and optimized for use on graphics processing unit (GPU) clusters, making the solver run extremely fast. It can be used to predict, for example, lubrication in drive systems with rotating shaft / gears and force and torque analysis on individual parts of the system or predicting slippage in liquid containers during transportation.
For gear drive models, the FLuidX nano source code can run faster than Finite-Volume code even for more detailed geometry models.
2. Application of nanoFluidX software
The particle stream nature of the FluidX nanocoding allows for currents of high strain during simulation, such as sliding currents, multi-phase currents or rapid motion over complex geometry.
This makes nanoFluidX ideal for a wide range of applications in various industries, including:
2.1. General free surface flow
Simulating oil slippage in drive system, fluid flowing freely in open or closed environment under high acceleration and the like.
2.2. High density multi-rate flow
The Smoothed Particle Hydrodynamics (SPH) method of nanoFluidX allows the easy handling of high density ratio multi-phase streams (eg, air in water) without the need for additional calculation.
2.3. Rotary gears, crankshaft and connecting rod for the powertrain
Altair nanoFluidX has deployed options for specifying different types of drives, thus making it easy to emulate rotating gears, crankshafts and connecting rods. Force and torsion measurements are experienced by solid particles as they interact with the surrounding liquid.
2.4. Slippage in liquid transport tanks
Especially suitable for automotive, commercial and aerospace applications, the tank slide simulation allows for accurate measurement of containers or vehicles encountered during strong acceleration, such as braking or alteration sudden lane.
3. Main features of the software
Altair nanoFluidX gives you faster preprocessing, advanced GPU technology for minimal simulation time and easy post-processing.
3.1. GPU computing
GPU computing offers a significant performance advantage and saves power over more bulky CPU competitors. The GPU revolution in scientific and engineering computing is rapidly evolving, and nanoFluidX is one of the pioneering commercial software packages that utilize this technology, bringing significant speed to overall product development. .
Standard finite volume CFDs encounter great difficulties when dealing with complex geometries, which are often not initializable. Even if they did, the preprocessing time would take weeks and the computation cost of such a simulation would be enormous.
3.2. Simplify the pretreatment process
Mesh is not required. Import geometry, select elements and create particles. There's not a lot of time to preprocess and define a good grid.
3.3. Hard movement
Besides rotation, the nanoFluidX source code allows the element orbits to be specified by an input file. Study of the interaction of an arbitrary displacement solid and its surrounding liquid.
3.4. Hardware requirements
nanoFluidX recommends users to use NVIDIA Tesla V100, P100 and K80 accelerators, as they are well-established or scientifically compute GPUs in data centers, and nanoFluidX has been thoroughly tested on them. This code also has dynamic load balancing ensuring optimal hardware usage, and can also run on multi-node clusters.
“As a solver for understanding the flow of lubrication inside a NuVinci product, nanoFluidX is of great value to our project. The software offerings, HPC and nanoFluidX make this simulation approach accessible to non-expert users like Fallbrook Technologies, and I would recommend it as a viable option for simulation tasks. next."
