Computational science research components were vital parts of the SciDAC-1 accelerator project and are continuing to play a critical role in the SciDAC-2 accelerator project, the Community Petascale Project for Accelerator Science and Simulation (ComPASS). Presented here are recent advances and achievements in the area of computational science research in support of petascale electromagnetic modeling for accelerator design analysis, which include shape determination of superconducting RF cavities, mesh-based multilevel preconditioner for solving highly indefinite linear systems, moving window using h- or p-refinement for time-domain short-range wakefield calculations, and improved scalable application I/O.
