NUMECA Releases OMNIS 3.1 for Simulation, Optimization

BRUSSELS, Belgium, Mar 11, 2019 – NUMECA is delighted to announce the official release of OMNIS 3.1 for multidisciplinary simulation and optimization. It’s going to bring you exciting new features and product improvements including our new Lattice-Boltzmann based solver.




Highlights of version 3.1

OMNIS/LB – particle-based Lattice-Boltzmann solver

Save a lot of time and run the most complex simulations

OMNIS/LB is a particle-based Lattice-Boltzmann solver for complex and high-fidelity flow simulations. It easily handles complex geometry with moving parts, solid contacts, free surface flows. The engineering days spent in geometry preparation, mesh, and simulation setups are now reduced down to minutes of your precious time. This first release is primarily dedicated to internal multiphase flow applications such as gearboxes, bearings, and volumetric pumps.

Simulation – Bridge to FINE

Access all technologies in one environment 

The Bridge to FINE feature enables an analysis workflow which takes advantage of OMNIS’s meshing and post-processing capabilities as well as the simulation power and all features of FINE/Open with OpenLabs, FINE/Marine, and FINE/Turbo.
