Master Thesis; Development of Effective Parallel Block Meshing

Linköping, Sweden
Closing date: 6 November 2022

Background

HPC environments have significantly increased the potential of computational analysis, greatly reducing the computation time and the size of problems that can be solved. There are many methods to solve such computational problems. In computational electromagnetics (CEM), one such method is the finite-difference time method (FDTD), which divides the computational domain into a grid of blocks. Our department has developed a software using the FDTD method, where HPC capabilities greatly improve the performance of the program. However, for large problems, there is one bottleneck remaining: meshing, the creation of the block grid.

Description of the master thesis

This Master Thesis concerns the development of an effective parallel block meshing software that scales well for usage in an allocated HPC environment. This meshing software should use a fast method to create meshes for very large geometries with several materials and store the meshes in a memory-effective fashion. Initially, a theoretical study should be performed where different algorithms are evaluated. Then follows the development of the meshing software and the evaluation of its performance.
