Three-dimensional mesh adaptation in PFEM
Thomas Leyssens, Jonathan Lambrechts, Jean-François Remacle
Chaotic free surface flows are challenging problems to simulate numerically, mainly due to the significant changes in geometry and frequent topological changes. Methods that track…
A scalable high-order multigrid-FFT Poisson solver for unbounded domains on adaptive multiresolution grids
Gilles Poncelet, Jonathan Lambrechts, Thomas Gillis +1
Multigrid solvers are among the most efficient methods for solving the Poisson equation, which is ubiquitous in computational physics. For example, in the context of incompressible…
Solving the Porous Medium Equation with the eXtreme Mesh deformation approach (X-Mesh)
Alexandre Chemin, Jonathan Lambrechts, Nicolas Moës +1
We introduce a new scheme for solving the non-regularized Porous Medium Equation. It is mass conserving and uses only positive unknown values. To address these typically conflictin…
A Coupled PFEM-DEM Model for Fluid-Granular Flows with Free-Surface Dynamics Applied to Landslides
Thomas Leyssens, Michel Henry, Jonathan Lambrechts +2
Free surface and granular fluid mechanics problems combine the challenges of fluid dynamics with aspects of granular behaviour. This type of problem is particularly relevant in con…
