The successful completion of MESQUITE will provide a robust and effective mesh improvement toolkit to the broader scientific community. This will allow both mesh generation researchers and application scientists to benefit from the latest developments in mesh quality control and improvement.
Benefits to Mesh Generation
MESQUITE will aid mesh generation researchers by providing a tool that improves the quality of the meshes generated by their algorithms. For example, some hexahedral mesh generation methods create topologically valid but poor quality elements; such methods will benefit from mesh quality improvement techniques that smooth the nodes enough to achieve acceptable geometric mesh quality. Furthermore, MESQUITE will provide a research platform for the development of new mesh improvement algorithms. By providing modular software with well-defined interfaces, MESQUITE will enable other researchers to easily experiment with new algorithms, new combinations of algorithms, and new quality metrics. These new algorithms can be directly compared both in terms of relative quality improvement and in terms of
efficiency with the methods already in place. Currently such comparisons are tedious to perform and are therefore seldom done.
Benefits to Applications
Any PDE-based simulation community will potentially benefit from the development of MESQUITE. In general terms, mesh improvement
techniques will reduce the time needed to create a suitable mesh,
thus reducing the time to solution, and improving the accuracy of the approximate solutions.
Research on mesh optimization performed by the present group of researchers has impacted the following simulation groups and packages:
