Abstract

The article gives an introduction to numerical modeling of flow and transport problems and to software tools that are currently in use for modeling such phenomena. Details are explained on numerical approximations leading to different numerical models. Extensions for reactive transport are mentioned. Basic guidelines and criteria are given that should be taken into account by the modeler in order to improve the accuracy of results. Inverse modeling is presented as an advanced feature. Some examples of pre- and postprocessing, as implemented in several codes, are given, in addition to fundamental properties of solution methods. Finally, most common codes are listed with basic features and web-sites.
