Visualisation de tourbillons dans une couche limite turbulente — DNS of a turbulent boundary layer

For numerical simulations, the LMFL relies on the computing resources of its affiliated institutions.

but also on National (GENCI) and European (EuroHPC) computing centres. Most of the codes used are open source codes such as OpenFoam, Xcompact3D, CaNS, Meso-NH, and ERF. The LMFL also develops calculation codes for specific applications as well as post-processing codes for turbulence analysis.

Xcompact3D

The Xcompact3D code was used to perform direct numerical simulations (DNS) of several types of flows, such as turbulent boundary layers and wakes.

OpenFOAM

OpenFoam is used for RANS simulations and high-fidelity simulations (LES) of flows in complex geometries.

CaNS

The LMFL uses the CaNS 2.0 open source code adapted to GPU partitioning for large-scale direct simulations. For example, it has been used for a direct numerical simulation of turbulent boundary layers at high Reynolds numbers.
