Hex Me If You Can
Pierre-Alexandre Beaufort, Maxence Reberol, Heng Liu +2
HEXME consists of tetrahedral meshes with tagged features, and of a workflow to generate them. The main purpose of HEXME meshes is to enable consistent and fair evaluation of hexah…
Ginzburg-Landau energy and placement of singularities in generated cross fields
Alexis Macq, Maxence Reberol, François Henrotte +4
Cross field generation is often used as the basis for the construction of block-structured quadrangular meshes, and the field singularities have a key impact on the structure of th…
Automatic surface mesh generation for discrete models: A complete and automatic pipeline based on reparameterization
Pierre-Alexandre Beaufort, Christophe Geuzaine, Jean-François Remacle
Triangulations are an ubiquitous input for the finite element community. However, most raw triangulations obtained by imaging techniques are unsuitable as-is for finite element ana…
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…
Computing cross fields -- A PDE approach based on the Ginzburg-Landau theory
Pierre-Alexandre Beaufort, Christos Georgiadis Jonathan Lambrechts, François Henrotte +2
This paper proposes a method to compute crossfields based on the Ginzburg-Landau theory. The Ginzburg-Landau functional has two terms: the Dirichlet energy of the distribution and…
