Mesh quality improvement for SciDAC applications

Accurate and efficient numerical solution of partial differential equations requires well-formed meshes that are non-inverted, smooth, well-shaped, oriented, and size-adapted. The Mesquite mesh quality improvement toolkit is a software library that applies optimization algorithms to create well-formed meshes via node movement. Mesquite can be run stand-alone using drivers or called directly from an application code. Mesquite can play an essential role in the SLAG accelerator design program as a component in automatic shape optimization software and in manufacturing defect-correction studies to smoothly deform meshes in response to geometric domain deformations guided by the optimization of design parameters. Mesquite has also been applied to problems in fusion, biology, and propellant burn studies.
