Starting from the Divertor I geometry, the finite element experiments were made to establish the thermal pressure on the Divertor tiles. This concerned the highly pressurised zone in the area of the Separatrix, whereby in particular the severe increase in temperature of the unprotected front edges of the tiles was more closely inspected. The combination of both 2-dimensional models produced very clear evidence of the temperature development in the 3-dimensional case with regard to time and area. Building on these thermal calculations, several crucial questions for the layout of Divertors were examined. So as to gain information regarding the thermo-mechanical pressure against the background of the complex material behaviour of CFC graphites, relevant FE-calculations were carried out on the 3-dimensional model of the Divertor I tiles.
