Fast Direct Solution of the Helmholtz Equation with a Perfectly Matched Layer/an Absorbing Boundary Condition
We consider efficient numerical solution of the Helmholtz equation in a rectangular domain with a perfectly matched layer (PML) or an absorbing boundary condition. Standard bilinear (trilinear) finite element discretization on an orthogonal mesh leads to a separable system of linear equations for which we describe a cyclic reduction type fast direct solver. We present numerical studies to estim...
متن کاملApplication of the perfectly matched layer (PML) absorbing boundary condition to elastic wave propagation
A method is presented for application of the perfectly matched layer !PML" absorbing boundary condition !ABC" to the P-SV velocity–stress finite-difference method. The PML consists of a nonphysical material, containing both passive loss and dependent sources, that provides ‘‘active’’ absorption of fields. It has been used in electromagnetic applications where it has provided excellent results f...
متن کاملPerfectly Matched Layers for Elastodynamics: A New Absorbing Boundary Condition
The use of perfectly matched layers (PML) has recently been introduced by Berenger as a material absorbing boundary condition (ABC) for electromagnetic waves. In this paper, we will rst prove that a ctitious elastodynamic material half-space exists that will absorb an incident wave for all angles and all frequencies. Moreover, the wave is attenuative in the second half-space. As a consequence, ...

We present the discretized equations of the 12 PML (perfectly matched layer) in the three-dimensional case using the Cartesian geometry. These equations can be used in different fields where Maxwell equations need to be solved.
