Webinar – Introduction to PowerFLOW – Lattice Boltzmann aerodynamic simulation

23 Nov, 2023 @ 10:00 am - 11:00 am


For prospects in Belgium, Netherlands or Luxembourg –

4RealSim welcomes you to a free webinar Introduction to PowerFLOW, the Lattice Boltzmann aerodynamic solver. This webinar outlines the benefits of PowerFLOW and gives the participants a first view to the product portfolio.

Lattice Boltzmann method

The lattice Boltzmann methods (LBM) is a class of computational fluid dynamics (CFD) methods for fluid simulation. Instead of solving the Navier–Stokes equations directly, a fluid density on a lattice is simulated with streaming and collision (relaxation) processes. The method is versatile as the model fluid can straightforwardly be made to mimic common fluid behaviour like vapour/liquid coexistence, and so fluid systems such as liquid droplets can be simulated. Also, fluids in complex environments such as porous media can be straightforwardly simulated, whereas with complex boundaries other CFD methods can be hard to work with.

Why Lattice Boltzmann?

During the webinar we will explain the benefits of the Lattice Boltzmann method and in which domains this solution can be used.

  • High fidelity transient solution, accurate across most flow regimes (laminar to transonic) to solve the most complex CFD design problems
  • Automated domain discretization and turbulence modeling with wall treatment eliminates the need for manual volume meshing and boundary layer meshing
  • Run on large number of compute cores
  • Utilize moving geometries and Local Reference Frames (LRF), particle modeling, heat exchanger modeling, porous media with flow, thermal and acoustic effects; Realistic Wind for on-road turbulent wind conditions to simulate real world effects
  • Simulate conjugate heat transfer problems with surface and volume conduction, thermal radiation and human thermal comfort using built-in variable interval coupling with PowerTHERM
  • Use standardized Application Templates to automate pre & post processing for common applications and customize for specific engineering environments
