Current techniques in composite-block-structured grid generation and unstructured grid generation for general 3D geometries are summarized, including both algebraic and elliptic generation procedures for the former and Delaunay tessellations for the

A review of a procedure for the simulation of time-dependent, inviscid and turbulent viscous, compressible flows involving geometries that change in time is presented. The adopted discretization technique employs unstructured meshes and both explicit

This paper presents a new approach towards the parallel local remeshing of unstructured tetrahedral grids on distributed memory parallel computers based on the message passing paradigm (MPI). The overall remeshing approach consisting of the parallel

Computational modelling has been used in plumbosolvency control optimisation studies involving three English water companies. A zonal model simulates lead emissions across an entire area of supply; it utilises a single pipe model that simulates the l

The EQSM method for the generation of unstructured triangular surface grids is presented. The method is based on remeshing techniques and avoids the need for traditional mesh triangulation approaches, such as the advancing front and the Delaunay meth

A fully automatic surface mesh generation system is presented in this paper. The automation is achieved by an automatic determination of a consistent mesh size distribution, which is based on geometry rasterisation. The user specifies a minimal and m

SUMMARY In this paper, the characteristic based split scheme is employed for the solution of three-dimensional incompressible viscousow problems on unstructured meshes. Many algorithm related issues are dis- cussed. Fully explicit and semi-implicit f

An implicit scheme for the time accurate solution of three dimensional compressible fluid flow problems with moving boundaries on unstructured tetrahedral meshes is described. The numerical scheme is nominally second order accurate in both space and

This paper proposes a discretisation of Maxwell's equations which combines the popular edge elements of Nedelec with expansions of plane waves. The method is applied to simple two dimensional electromagnetic wave propagation and scattering simulation

In this paper, a method to generate large unstructured meshes on parallel computers is demonstrated. Using the Message Passing Interface, a coarse-grained parallel harness has been developed, that allows the use of sequential generators in a parallel
