Our Software Solutions.


In the age of virtual product development, the expectation around CFD capabilities has skyrocketed. We need to simulate wading, powertrain lubrication, HVAC efficiency and critical flight maneuvers. Those new challenges call for advanced solutions.

Overview of XFlow

XFlow offers particle-based Lattice-Boltzmann technology for high-fidelity computational fluid dynamics (CFD) applications as a part of SIMULIA’s Fluids Simulation portfolio.

When steady-state solutions just won’t cut it, this state-of-the-art technology enables users to address complex CFD workflows involving high-frequency transient simulations with real moving geometries, complex multiphase flows, free surface flows and fluid-structure interactions.

XFlow Product Features

XFlow Pre/Post

GUI to quickly and efficiently create, edit, monitor, diagnose, and visualize XFlow analyses.

  • Pre, Post and solver fully integrated
  • Less than typical requirements for CAD
  • Monitor and visualize results all in one package

Particle-Based Solver

Particle-based kinetic algorithm generates extremely accurate results, even with turbulence.

  • Discretization approach avoids classic ‘domain’ meshing process
  • Easily control the level of detail
  • Lattice adapts to the presence of moving parts

Refined Accuracy

XFlow features a high-fidelity WMLES approach to turbulence modeling.​

  • Wall-Modeled Large Eddy Simulation
  • Disables where wall lattice size is appropriately small
  • Consistent local eddy-viscosity and near wall behavior

Fast Solution Times

All this means extremely fast solution times when compared with similar fidelity methods.

  • Drastically reduce model prep time
  • Domain discretiza
  • Optimize solution vs time constraints

Near-Linear Scalability

XFlow is fast, efficient and accessible, even on a standard desktop PC.

  • Fully parallelized
  • Distributed Memory Parallelization for HPC performance
  • Scales efficiently, even on a large number of nodes
