Abstract

I will talk about how our research of geometric data processing could (1) benefit scientific computing applications, and (2) benefit from high performance computing. The first part is on large-scale mesh generation. In many scientific computing tasks, analysis or simulations need to be performed on complex geometric regions. Constructing high-quality finite element meshes can result in more efficient and stable computations and PDE solving. We have developed a new distributed and parallel computational framework to generate semi-structured regular meshes for large-scale geometric regions. Compared with existing meshing algorithms/software, our framework can handle huge and complex geometries distributedly using high-performance clusters, and can support flexible singularity placement to produce low-distortion mesh elements. In the second part, I will demonstrate how we utilize powerful computational tools to develop effective digital pipelines/algorithms to process bones and solve challenging forensic problems in practical law enforcement.

Speaker's Bio

Xin Li is the Oskar R. Menton associate professor in the School of Electrical Engineering and Computer Science at Louisiana State University (LSU).
