Asynchronous global-local non-invasive coupling for linear elliptic problems

This paper presents the first asynchronous version of the Global/Local non-invasive coupling, capable of dealing efficiently with multiple, possibly adjacent, patches. We give a new interpretation of the coupling in terms of primal domain decomposition method, and we prove the convergence of the relaxed asynchronous iteration. The asynchronous paradigm lifts many bottlenecks of the Global/Local coupling performance. We illustrate the method on several linear elliptic problems as encountered in thermal and elasticity studies

Building Applications with VTK Library Using Tcl, C++ and Fortran Components

Rapport interne.This report describes a technique to build visualization applications using VTK library and components written in Tcl, C++ and Fortran. VTK is a software system for computer graphics, visualization and image processing. VTK library is written in C++ however it provides interfaces to languages like Tcl, Python and Java. Though it is possible to write a whole VTK application in scripting language like Tcl, sometimes it is desirable to implement some functionality in compiled language like C/C++ or Fortran, for instance to have access to features not available in scripting language or for efficiency reason. This report presents in through details how to access VTK objects from different languages and how to mix Tcl, C++ and Fortran components in one application

Simple visualizations of unstructured grids with VTK

Rapport interne.This report shows examples of simple visualizations of unstructured grids with use of VTK - The Visualization Toolkit. The examples are intended to illustrate few basic visualization techniques of visualization which can be used to visualize results of finite element computations. With each example there is a short description, a diagram showing the organization of a visualization pipeline, a Tcl script and results of running it on sample data
