Innovation & Quality


Developed by NUMRI (Numerical Research and Innovation), a NUMECA company focused on developing cutting-edge and innovative simulation technology, FINE™/LB is a Lattice Boltzmann based CFD solution, complementing NUMECA’s existing CFD line-up.

This new Lattice Boltzmann solver is capable of handling highly complex geometries on a mesoscopic scale without the hassle of having to set-up and fine-tune a mesh, as is the case for traditional CFD solutions. Due to its extremely efficient parallelization, the turn-around time is comparable to, or even faster then, Navier-Stokes based LES simulations. 

Next to traditional licensing schemes, this new technology will be offered as SaaS (Software as a Service) running on a broad scale of commercial Cloud providers as well as on NUMECA’s state-of-the art cluster, with a dedicated client area.
