Analysis of particle- and energy-transport in tokamak plasmas shows th
e importance of the scrape-off layer (SOL) to achieve satisfying condi
tions for a burning plasma in a fusion reactor. To take into account t
he influence of complex geometrical features on transport, we develope
d a 2D-fluid-code based on a Finite Element Method (FEM). Because this
numerical scheme needs no regular grid structure, one can deal much m
ore accurately with the plasma flow in non simply connected domains an
d near limiter- or divertor-plates, where the magnetic field is inclin
ed to the target. This permits a geometrically and physically more rea
listic description of the interaction of plasma- and neutral-particles
. Results from a coupled calculation between the FEM-code and a neutra
l-gas Monte-Carlo-code (EIRENE) are discussed for the SOL of TEXTOR.
