BSP-Assisted Constrained Tetrahedralization
In this paper we tackle the problem of tetrahedralization by breaking non-convex polyhedra into convex subpolyhedra, tetrahedralizing these convex subpolyhedra and merging them to...

Efficient Spacetime Meshing with Nonlocal Cone Constraints
Spacetime Discontinuous Galerkin (DG) methods are used to solve hyperbolic PDEs describing wavelike physical phenomena. When the PDEs are nonlinear, the speed of propagation of th...

Twelve Ways to Fool The Masses when Describing Mesh Generation Performance
Mesh generation for finite element analysis is far from a solved problem. Although several automatic meshing algorithms exist, other difficulties of setting up a problem for finit...

PDE-Based Gradient Limiting for Mesh Size Functions
We propose a new method for limiting the gradients in a mesh size function by solving a non-linear partial differential equation on the background mesh. Our gradient limiting Ham...
