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.
