Research Note Abstract
This paper concerns mesh refinement in parallel. Particular topics include: the scalability of reading and associating a complex mesh and geometry, and a cursory explanation of our implementation details. The following implementation utilizes the Sierra ToolKit mesh environment and ACIS geometry. Scalability testing revealed that while the general refinement process scaled quite well, certain key pre-refinement processes have negative relationship with mesh size and processor count.
