Advanced Fluid and Gas Simulation solutions from SIMULIA
What is Computational Fluid Dynamics?
Computational fluid dynamics (CFD) assists designers in anticipating and measuring how a gas or liquid flows, as well as how the gas or liquid affects other equipment as it passes through each application. In manufacturing, computational fluid dynamics measures the velocity, pressure, temperature, and density of moving fluids.

PowerFLOW and XFlow Solutions
SIMULIA Fluids Simulation is powered by two complimentary technologies that deliver scalable fluids simulation to clients for a wide range of real-world applications.
PowerFLOW CFD solution performs simulations that accurately predict real-world conditions. PowerFLOW imports fully complex model geometry and accurately and efficiently performs aerodynamic, aeroacoustics, and thermal management simulations, this allows engineers to evaluate product performance early in the design process before any physical prototypes are created — when the impact of change is most significant for design and budgets.
XFlow is a particle-based Lattice Boltzmann technology solver for high fidelity Computational Fluid Dynamics (CFD) applications. For lubrication workflows like gearboxes and electric motor drives, XFlow delivers multiphase and moving parts modeling capabilities.
Together PowerFLOW and XFlow offer a world class Lattice Boltzmann method (LBM) technology for high fidelity simulations that accurately predict real world performance.
Fluid Dynamics Engineer
Fluid Dynamics Engineer on the 3DEXPERIENCE platform enables multi-scale multi-physical vision by integrating CFD into design, simulation, optimization, data management, and business intelligence applications. Furthermore, a Plastics Injection Molding application allows for the early validation and optimization of plastic part and mold tooling designs.
SIMULIA 3DEXPERIENCE Fluids Solver Technology
On the 3DEXPERIENCE platform, fluid simulation methods can be defined, stored, replayed, and maintained allowing customers to develop and centralize on their own best-practices to increase quality, reliability, and efficiency.
The physical space to be simulated is divided into many small sub-domains called control volumes or cells. The Navier-Stokes equations, a set of continuum equations that describe fluid motion, are discretized by the finite volume method.
Iteratively solving the resulting set of algebraic equations yields the pressure, velocity, temperature (and other physical quantities) in each cell for steady or unsteady flows. Other physical phenomena such as turbulence and chemical species can be represented using discretized transport equations in the same way.
Lattice Boltzmann method
The Lattice Boltzmann method, which is based on a discrete form of the kinetic theory of gases, tracks the microscopic motion of fluid particles through discrete space and time to simulate the flow of gases and liquids.
The fluid space is automatically discretized into cubic voxels and the boundaries into surfels, removing the need for traditional surface and volume grid generation. The Very Large Eddy Scale (VLES) turbulence modeling approach ensures high fidelity capture of anisotropic fluid structures, which is critical for aerodynamics and aeroacoustics workflows.
