1. Domain Decomposition and Preconditioned Iterative Methods for the Helmholtz Equation
Sammanfattning : New preconditioned iterative solution methods for the Helmholtz equation are constructed. To evaluate the performance of the methods, two-dimensional problems with a waveguide geometry are used as model problems. Second- and fourth-order accurate finite difference discretizations are used. LÄS MER
2. Oversampled radial basis function methods for solving partial differential equations
Sammanfattning : Partial differential equations (PDEs) describe complex real-world phenomena such as weather dynamics, object deformations, financial trading prices, and fluid-structure interaction. The solutions of PDEs are commonly used to enhance the understanding of these phenomena and also as leverage to make technological improvements to consumer products. LÄS MER
