Next-Generation Computational Fluid Dynamics (CFD)

SIMULIA XFlow uses the breakthrough Lattice-Boltzmann approach to push the limits of CFD. It allows you to realistically simulate highly dynamic or turbulent systems and fluid-structure interaction (FSI) without traditional meshing. Advanced behaviors such as liquid surface tension and free body motion let you analyze everything from a boat riding the waves, to oil sloshing in a gearbox, to an aircraft executing flight maneuvers, and much more.

Frequently Asked Questions

Does SIMULIA XFlow simulate the Navier-Stokes Equations?

No. SIMULIA XFlow solves the Boltzmann equations for fluids, improving performance and removing traditional CFD requirements such as a continuous fluid medium.

How is SIMULIA XFlow accessed?

The SIMULIA XFlow desktop application can be installed locally on Windows and Linux environments. Alternatively, you can launch XFlow directly from the cloud-based 3DEXPERIENCE platform.

What kind of computing power does SIMULIA XFlow support?

The base license of XFlow supports solving on up to 8 CPUs; this can be expanded to HPC and distributed computing environments utilizing up to 512 cores.

While SIMULIA XFlow can simulate heat transfer, specialized features for circuit boards and related components are not available. SOLIDWORKS Flow Simulation or SIMULIA CST Studio Suite would be recommended instead.

How does SIMULIA XFlow handle turbulent flow?

Large Eddy Simulation (LES) of individual turbulent vortices is enabled by a suite of models including Smagorinsky and Wall-Adapting Local Eddy (WALE).

Does SIMULIA XFlow support multiphysics applications?

Yes. SIMULIA XFlow natively supports rigid body motion of solid components, both free and enforced. Fluid-structure interaction for deformable geometry is possible via co-simulation with SIMULIA Abaqus.
