Learning dominant wave directions for plane wave methods for high-frequency Helmholtz equations
We present a ray-based finite element method (ray-FEM) for the high-frequency Helmholtz equation in smooth media, whose basis are learned adaptively from the medium and source. The method requires a fixed number of grid points per wavelength to represent the wave field; moreover, it achieves an asymptotic convergence rate of O(ω− 1 2 ), where ω is the frequency parameter in the Helmholtz equati...
متن کاملNumerical Analysis and Scientific Computing Preprint Seria Optimization of plane wave directions in plane wave Discontinuous Galerkin methods for the Helmholtz equation
Recently, the use of special local test functions other than polynomials in Discontinuous Galerkin (DG) approaches has attracted a lot of attention and became known as DG-Trefftz methods. In particular, for the 2D Helmholtz equation plane waves have been used in [10] to derive an Interior Penalty (IP) type Plane Wave DG (PWDG) method and to provide an a priori error analysis of its p-version wi...

CMSC828D notes (adapted from material written with Nail Gumerov). Work in progress 1 Acoustic Waves 1.1 Barotropic Fluids The usual assumptions for acoustic problems are that acoustic waves are perturbations of the medium (fluid) density ρ (r,t), pressure p (r,t), and mass velocity, v (r,t), where t is time. It is also assumed that the medium is inviscid, and that perturbations are small, so th...
متن کاملA Weighted Variational Formulation Based on Plane Wave Basis for Discretization of Helmholtz Equations
In this paper we are concerned with numerical methods for solving Helmholtz equations. We propose a new variant of the Variational Theory of Complex Rays (VTCR) method introduced in [15, 16]. The approximate solution generated by the new variant has higher accuracy than that generated by the original VTCR method. Moreover, the accuracy of the resulting approximate solution can be further increa...
متن کاملParallel Preconditioners for Plane Wave Helmholtz and Maxwell Systems with Large Wave Numbers
A kind of non-overlapping domain decomposition preconditioner was proposed to solve the systems generated by the plane wave least-squares (PWLS) method for discretization of Helmholtz equation and Maxwell equations respectively in [13] and [14]. In this paper we introduce overlapping variants of this kind of preconditioner and give some comparison among these domain decomposition preconditioner...
