L'utilisation de mailles rectangulaires et le changement de maille dans la methode TLM en deux dimensions permet de reduire le temps de calcul sur ordinateur dans de grandes proportions pour de nombreux problemes. La theorie est exposee et des resultats sont donnes pour des structures ‘fin-line’.The letter shows how the introduction of rectangular meshes, and of a variable-size mesh process in the original 2-dimensional TLM method, leads to a dramatic reduction of the needed CPU time. The theoretical aspects of these modifications are given, as well as some numerical results obtained for 'fin-line' structures.
