The Tempered Finite Element Method
Antoine Quiriny, Václav Kučera, Jonathan Lambrechts +2
In this paper, we propose a new approach -- the Tempered Finite Element Method (TFEM) -- that extends the Finite Element Method (FEM) to classes of meshes that include zero-measure…
A Delaunay Refinement Algorithm for the Particle Finite Element Method applied to Free Surface Flows
Thomas Leyssens, Michel Henry, Jonathan Lambrechts +1
This paper proposes two contributions to the calculation of free surface flows using the particle finite element method (PFEM). The PFEM is based on a Lagrangian approach: a set of…
X-Mesh: A new approach for the simulation of two-phase flow with sharp interface
Antoine Quiriny, Jonathan Lambrechts, Nicolas Moës +1
Accurate modeling of moving boundaries and interfaces is a difficulty present in many situations of computational mechanics. We use the eXtreme Mesh deformation approach (X-Mesh) t…
The eXtreme Mesh deformation approach (X-MESH) for the Stefan phase-change model
Nicolas Moes, Jean-Francois Remacle, Jonathan Lambrechts +2
The eXtreme Mesh deformation approach (X-MESH) is a new paradigm to follow sharp interfaces without remeshing and without changing the mesh topology. Even though the mesh does not…
Quaternionic octahedral fields: SU(2) parameterization of 3D frames
Pierre-Alexandre Beaufort, Jonathan Lambrechts, Christophe Geuzaine +1
3D frame fields are auxiliary for hexahedral mesh generation. There mainly exist three ways to represent 3D frames: combination of rotations, spherical harmonics and fourth order t…
High quality mesh generation using cross and asterisk fields: Application on coastal domains
Christos Georgiadis, Pierre-Alexandre Beaufort, Jonathan Lambrechts +1
This paper presents a method to generate high quality triangular or quadrilateral meshes that uses direction fields and a frontal point insertion strategy. Two types of direction f…
