The project FLOCCON is dedicated to the development and validation of an innovative strategy to accelerate solvers for fluid mechanics. The project focuses on incompressible solvers, containing two parts: (1) a linear Poisson equation, and (2) a non-linear advection equation. The key idea of this pr

Increasing the efficiency of model-based industrial processes requires to improve their uncertainty quantification and numerical optimization. Such issues appear in most of the engineering domains (e.g. energy, transport, agriculture) and scientific fields (e.g. biology, high-energy physics). A majo

Saving energy by designing lighter objects while maintaining high mechanical properties is a crucial issue for industry. In this context, we are proposing a new object design solution, subject to a set of mechanical and / or thermal constraints This solution exploits materials whose lacunar structur

The VPFlows project develops innovative numerical methods for HPC simulation of yield stress flows, associated to the modelling of geophysical flows like avalanches. It is a deeply interdisciplinary project: the part on numerical simulations (currently the most precise in the field thanks to HPC) go

Both statistical physics and Bayesian statistical inference revolve around probabilistic modeling and relies on description based on intractable integrals, which are sampled through Monte Carlo algorithms. As size and complexity of problems increase, these high-dimensional problems require more effi

An important collaboration has existed for several years at the University of Limoges around the development of efficient computational codes for the simulation of colloidal suspensions. This project associates two complementary teams: a team of the XLIM laboratory specialized in GPU computing (B. C

Urban floods produced by exceptional precipitations may cause large damages both in terms of life losses and property destruction. Numerical modeling can be used to predict, anticipate and control the floods by helping to size and position protective systems including dams, dikes or rainwater draina

We seek to improve upon the current design and bring the optimal performance to wind turbine farms, by using the flexible blades as the novel idea. The blades flexibility can be an advantage for starting the turbine operation for mild wind (like tree leaves), but a disadvantage for keeping the turbi

Even though computational resources grow rapidly, the extremely fine scales in fluid and plasma turbulence remain beyond reach using existing numerical methods. A combination of computational power and ingenious physical insights is usually needed to go beyond the brute force limit. We propose here

Intensive usage of floating-point (FP) arithmetic in today’s real software affect numerical quality and reproducibility of program.
