Title: Report on FY11 Extensions to MeshKit and RGG

One of the barriers to performing high-fidelity computational simulation of reactor core phenomena is the production of good-quality geometry and mesh models required by these simulations. Although a variety of geometry and meshing tools are available, they suffer from shortcomings in usability, robustness, or generality which makes them difficult to apply to reactor applications. The SHARP frameworks project is addressing these deficiencies by developing a library of mesh generation algorithms, and tools based on that library. The library is known as MeshKit, and one of the tools being developed is named RGG, for Reactor Geometry (and mesh) Generator. Over the past year, our meshing-related work was split between general design improvements in MeshKit, enhancing RGG to run in parallel, and the application of RGG to several specific reactor designs. These activities are described in this report.
