An automatic mesh generation method employing a dynamic bubble system can provide a high-quality mesh for electromagnetic finite element analysis. However, there is a problem that it takes very long time to compute bubbles' movement when a mesh with a huge number of elements is produced. It is possible to independently and simultaneously compute the bubbles' movement, therefore the computation of the bubbles' movement is suitable for a parallel computing. In order to shorten the computation time, the computation of bubbles' movement is parallelized with GPU. We propose a dynamic bubble system parallelized with GPU. As the result, the reduction of the computation time was achieved.Index Terms-Dynamic bubble system, finite element analysis, mesh generation, parallel computing.
