Abstract

The finite element field solvers in Beam Optics Analyzer (BOA), Poisson solver using scalar shape functions and Curl-Curl solver using vector shape functions for interpolation, have already had a built-in adaptivity but only serially. The new parallel adaptivity in BOA takes full advantage of the current low-cost high-performance multi-core processors making adaptive meshing highly efficient. Parallel adaptivity methodologies will be discussed, and numerical results will be demonstrated.
