- ItemFast array analysis using parallelised domain decomposition methods(Stellenbosch : Stellenbosch University, 2020-12) Ebrahim, Tameez; Ludick, Danie; Stellenbosch University. Faculty of Engineering. Dept. of Electrical and Electronic Engineering.ENGLISH ABSTRACT: The requirements for antennae increase daily and as such, antenna arrays are used to meet them. These arrays are often large, consisting of hundreds of antennae, and typically require multiple simulations for optimisation. Due to the computational requirements needed for these runs, it is necessary to apply specialised methods in order to reduce runtime while maintaining accuracy. In this thesis, three domain decomposition techniques based on the Method of Moments (MoM), namely, the Characteristic Basis Function Method (CBFM), the Domain Green's Function Method (DGFM) and the Improved Domain Green's Function Method (i-DGFM) will be investigated and implemented. These techniques will then be parallelised using shared and distributed high performance computing methods such as Open Multi Processing (OpenMP) and Message Passing Interface (MPI). In addition, implementation and parallelisation will also be performed for a Graphical Processing Unit (GPU).
