Unstructured Mesh Generation and Optimization

2:00 PM-4:00 PM

This minisymposium focuses on techniques for defining, creating, and maintaining high-quality unstructured meshes for complex geometries. This area of research is particularly important for obtaining accurate and efficient solutions for the increasingly realistic and complicated models that are possible in today's computational environment. The speakers will address several research challenges in this minisymposium, including the development of mathematically rigorous, algebraic expressions for mesh quality metrics, the generation of high quality tetrahedral meshes along curved surfaces, and maintaining mesh validity and quality when refining along curved boundaries.
