Ph.D. project

Developing a Particle-In-Cell (PIC) based numerical solver for fluid-structure interaction in the coastal and offshore environment. The project was jointly supported by University of Bath and HR Wallingford.

This PIC model is hybrid Eulerian and Lagrangian (both fixed grid and moving particles are used). It combines advantages from both Eulerian and Lagrangian methods. The developed PIC model was found to be both efficient and flexible in simulating complex problems such as wave overtopping, wave breaking and the interaction of such waves with fixed or floating structures of arbitrary shape. I wrote the solver in both two and three spatial dimensions using FORTRAN, and I also parallelised the 3D solver using the MPI approach.
