High-Order Nyström/Convolution-Quadrature Solution of Time-Domain Scattering from Closed and Open Lipschitz Boundaries with Dirichlet and Neumann Boundary Conditions
Peter P. Petropoulos, Catalin Turc, Erli Wind-andersen
We investigate high-order Convolution Quadratures methods for the solution of the wave equation in unbounded domains in two dimensions that rely on Nyström discretizations for the…

Boundary integral equation methods for the solution of scattering and transmission 2D elastodynamic problems
Victor Dominguez, Catalin Turc
We introduce and analyze various Regularized Combined Field Integral Equations (CFIER) formulations of time-harmonic Navier equations in media with piece-wise constant material pro…
