YALES2 Training Session

Place: CORIA lab, Rouen & online
Date: 29-31 of March 2022
Time: Day 1 (14:00-18:00 CET), Day 2 (9:30-18:00 CET), Day 3 (9:30-18:00 CET)





YALES2 aims at the solving of two-phase combustion from primary atomization to pollutant prediction on massive complex meshes. It is able to handle efficiently unstructured meshes with several billions of elements, thus enabling the Direct Numerical Simulation and Large-Eddy Simulation of laboratory and semi-industrial configurations. The recent developments are focused on the dynamic mesh adaptation of tetrahedral-based massive meshes for fronts and interfaces.


This training session targets researchers and engineers interested in learning YALES2 and/or the numerical methodologies developed in YALES2: solving for incompressible turbulent flows, two-phase flows, dynamic mesh adaptation, etc.

Instructors: Vincent Moureau (CNRS), Ghislain Lartigue (CNRS), Pierre Bénard (INSA of Rouen)
