Abstract

Modelling the structural effects of vertical displacement events (VDEs) on plasma facing components is critical for component integrity but can be time consuming. In early-stage design, a simple analysis method is useful to compare concepts. This paper describes methods that use the commercially available ANSYS software to obtain estimations of forces and torques on components arising from VDE induced currents and halo currents. The methods will be used to inform the design of in-vessel assemblies on Tokamak Energy Ltd's future machines.
