Over-Relaxation Lloyd Method For Computing Centroidal Voronoi Tessellations
… Lloyd Method for computing CVTs by applying over-relaxation schemes in the iteration process. Optimal choices of the over-relaxation parameter are studies theoretically. We also verify our results and show faster convergence of the proposed over-relaxtion Lloyd method through various numerical …

Numerical stability of Monte Carlo neutron transport and isotopic depletion for nuclear reactor analysis
… 3 begins by highlighting how implicit burn-up schemes may be viewed as root-finding schemes for a discrete map. It is shown that, for reasonably long time-steps, the corrector step of predictor-corrector schemes does not succeed in locating the root (or the stable solution) of this map. Hence, …

Accelerating the Jacobi Iteration for Solving Linear Systems of Equations using Theory, Machine Learning, and High Performance Computing
… well-suited for HPC), we develop a family of relaxation schemes which greatly improve the convergence of the method. These schemes, termed Scheduled Relaxation Jacobi (SRJ) schemes, provide acceleration for both symmetric and nonsymmetric linear systems of equations. In the symmetric case, a …

Three-dimensional mathematical model of a high temperature polymer electrolyte membrane fuel cell
… transport phenomena, a set of numerical under-relaxation schemes are developed using the programming language C++. Good convergence is achieved with these schemes, though the model is based on a serpentine single-channel flow approach. The model results are validated against experimental …
