Abstract :
The SMARDDA software library is used to model plasma interaction with complex engineered surfaces. A simple flux-tube model of power deposition necessitates the following of magnetic fieldlines until they intersect the geometry taken from a computer aided design (CAD) database. Application is made to: 1) models of ITER tokamak limiter geometry and 2) MAST-U tokamak divertor designs, illustrating the accuracy and effectiveness of SMARDDA, even in the presence of significant nonaxisymmetric ripple field. SMARDDA´s ability to exchange data with CAD databases and its speed of execution also gives it the potential for use directly in the design of tokamak plasma-facing components.
