NUMECA has released OMNIS 3.1. One new feature is the OMNIS/LB – particle-based Lattice-Boltzmann based solver. This release comes with a documentation included in the software and available online.

OMNIS/LB is a particle-based Lattice-Boltzmann solver for complex and high-fidelity flow simulations. It handles complex geometry with moving parts, solid contacts, free surface flows. This first release is primarily dedicated to internal multiphase flow applications such as gearboxes, bearings and volumetric pumps.
