GPUによる要素マトリックス計算  [in Japanese] Calculation of Element Stiffness/Mass Matrices Using a GPU  [in Japanese]

This paper describes the method for calculation of element stiffness/mass matrices using a GPU, Graphics Processing Unit. GPU was first developed only for processing 3D computer graphics several years ago. It has obtained both flexible programmability and fast numerical processing ability. This has led to the so-called GPGPU, General Purpose GPU i.e. applications of GPUs into non-graphics fields. In this paper, GPU is utilized for calculations of element stiffness/mass matrices in the finite element method. In the proposed method whole element matrices calculation is performed on a GPU. The fundamental formulation of the method is described in detail, and its basic performance is tested through sample analyses.
