NUMECA OMNIS 3.1

The NUMECA International team is pleased to announce the official release of NUMECA OMNIS 3.1. One new feature, OMNIS/LB, is a particle-based Lattice-Boltzmann solver for complex and high-fidelity flow simulations.

Discover the highlights of version 3.1

- OMNIS/LB – particle-based Lattice-Boltzmann solver
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.
- 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.
