Analysis of particle and energy transport in tokamak plasmas shows the importance of the scrape-off layer (SOL) in achieving satisfying conditions for a burning plasma in a fusion reactor. A 2D fluid code based on a finite element model (FEM) has been developed in order to take into account the influence of complex geometrical features on transport. This numerical scheme does not require a regular grid structure and thus permits a geometrically and physically more realistic description of the interaction of plasma and neutral particles. Results from a coupled calculation between the FEM-code and a neutral gas Monte Carlo code (EIRENE) are discussed for the SOL of TEXTOR.
