The quality improvement in mesh optimisation techniques that preserve its connectivity are
obtained by an iterative process in which each node of the mesh is moved to a new position …

We consider the numerical computation of equilibrium shapes of rotating drops and their
bifurcations, depending on the angular velocity. The drops are subject to centrifugal forces …

The development of parallel algorithms for mesh generation, untangling, and quality
improvement is of high importance due to the need for large meshes with millions to billions …

We define quasiconvex programming, a form of generalized linear programming in which
one seeks the point minimizing the pointwise maximum of a collection of quasiconvex …

Electrical impedance tomography (EIT) is a diffuse imaging modality in which the resistivity
distribution inside the object is estimated based on electrical measurements made on the …

In the finite element simulation of environmental processes that occur in a three-dimensional
domain defined over an irregular terrain, a mesh generator capable of adapting itself to the …

Despite its great success in improving the quality of a tetrahedral mesh, the original optimal
Delaunay triangulation (ODT) is designed to move only inner vertices and thus cannot …

High quality meshes are crucial for the solution of partial differential equations (PDEs) via
the finite element method (or other PDE solvers). The accuracy of the PDE solution, and the …

The improvement in the mesh quality without changing its connectivity is bounded. This
bound is associated with the topology of the mesh and with the constraints imposed by the …
