Public ISBD Titre : Finite elements in water resources Type de document : texte imprimé Auteurs : Gray, W. G. ; Pinder, G. F. Mention d'édition : The serveral contributors named in the list of contents Editeur : The serveral contributors named in the list of contents Année de publication : 1977 ISBN/ISSN/EAN : 727306014 Note générale : The report show that rational approximations to the exponential matrix are employed to explain the performance of traditional methods for integrating some partial differential equations used in water resources analysis wath respect to time. The same technique then allows the prediction of the performances of higher order integration methods, so that only the most promising of these need be coded. The behaviour of various algorithms is them compared in the solution of typical problems involving diffusion, convection or a combination of both.
