Fast, High-Fidelity CFD Simulation

SIMULIA's Computational Fluid Dynamics (CFD) simulations enable customers to engineer products with precise real-world performance predictions delivered quickly. Our Fluids technologies address diverse challenges across industries and applications, such as eVTOL flight and community noise testing, race-car aerodynamics optimization, and automotive WLTP fuel efficiency certification.

SIMULIA Fluids Simulation is driven by two complementary technologies that provide customers with scalable fluid simulation to address a broad range of real-world applications. PowerFLOW and XFlow offer world-class Lattice Boltzmann method (LBM) technology for high-fidelity simulations that accurately predict real-world performance. Fluid Dynamics Engineer enables multi-scale multi-physical insight by embedding CFD into design, simulation, optimization, data management, and business intelligence applications within the 3DEXPERIENCE platform. In addition, a Plastics Injection Molding application allows validation and optimization of plastic part and mold tooling designs early in the product development process.


SIMULIA Computational Fluid Dynamics Simulation Key Benefits

Faster design turnaround times

Simulation accelerates analysis and optimization, allowing shorter design cycles and providing a competitive advantage

Reduced reliance on testing

Compared to wind tunnel testing, simulation is faster, more cost-effective and can be implemented earlier in the design cycle. It can also reveal behavior not visible in a test

Versatile, high-performance simulation technology

Aerodynamic and aeroacoustic simulation can be performed on large, complex structures and in real-world conditions

Reduced work through automation

Automatic meshing, model-building, visualization and Design of Experiments (DoE) removes tedious set-up work and lets engineers get the results they need faster

Leverage design models

Unified modeling and simulation (MODSIM) means simulation can be performed directly on geometry from CATIA or SOLIDWORKS in a unified design environment, reducing the time needed for model building.

Full analysis with multiphysics simulation

Fluids simulation can be supplemented by other disciplines, such as vibro-acoustic simulation, structures simulation, electromagnetic simulation and multibody system simulation

SIMULIA Fluids Solver Technology


The physical space to be simulated is divided into many small subdomains called control volumes or cells. The finite volume method is used to discretize the continuum equations that describe fluid motion, known as the Navier-Stokes equations. The resulting set of algebraic equations is solved iteratively to obtain the pressure, velocity, temperature (and other physical quantities) in each cell for steady or unsteady flows. Other discretized transport equations can be solved in the same way to represent other physical phenomena like turbulence and chemical species.
