We present an open-source differentiable acoustic simulator, j-Wave, which can solve time- varying and time-harmonic acoustic problems. It supports automatic differentiation, which is …
Schwarz methods use a decomposition of the computational domain into subdomains and need to impose boundary conditions on the subdomain boundaries. In domain truncation …

In this article, a meshless barycentric interpolation collocation method (BICM) with coordinate transformation is proposed to solve the governing partial differential equations …
This paper explores a family of generalized sweeping preconditioners for Helmholtz problems with non-overlapping checkerboard partition of the computational domain. The …
A new hybridizable discontinuous Galerkin method, named the CHDG method, is proposed for solving time-harmonic scalar wave propagation problems. This method relies on a …
Numerical Assessment of PML Transmission Conditions in a Domain Decomposition Method for the Helmholtz Equation Page 1 Numerical Assessment of PML Transmission Conditions in …
We study overlapping Schwarz methods for the Helmholtz equation posed in any dimension with large, real wavenumber and smooth variable wave speed. The radiation condition is …
Numerical discretization of the large-scale Maxwell's equations leads to an ill-conditioned linear system that is challenging to solve. The key requirement for successive solutions of …
