OMNIS™/LB

A high-fidelity flow solution for complex in-and external flows.

 

 

 

 

 

 

FOCUS ON HIGHLY COMPLEX PHYSICS AND GEOMETRIES, MESH-FREE

Capable of handling complex geometries on a mesoscopic scale without the burden of having to set-up and fine-tune a mesh.

HIGH-FIDELITY LES MODELING - FULLY TRANSIENT

The particle based Lattice Boltzmann solver allows new levels of modeling capability.

LARGE NUMBER OF PHYSICAL MODELS AVAILABLE 

Allows to model a wide range of applications such as internal and external flow including free surface flows, external aerodynamics, microfluidics, porous media, fluid-membrane interaction, heat transfer problems etc.

BODY-TO-BODY MOTION

Capture moving bodies such as rotating gears, positive displacement pumps, pistons, and much more, accurately, with almost no user-input.
