 Abstract: Tungsten erosion at the central column and tungsten transport in the scrape-off layer of ASDEX Upgrade have been modeled with the 2D Monte-Carlo impurity transport code DIVIMP. The main objectives were the reproduction of the erosion and migration patterns that are observed experimentally. This was accomplished by implementing a new erosion routine which allows to calculate the tungsten source term at the central column and subsequently the poloidal distribution of the W density. First results on W transport in the boundary plasma as well as erosion and migration patterns of W are discussed in relation to different models of the plasma in front of the central column. A comparison between measured and modeled deposition of W in the divertor already shows satisfactory qualitative agreement.
