An OSRC Preconditioner for the EFIE
Ignacia Fierro-Piccardo, Timo Betcke
The Electric Field Integral Equation (EFIE) is a well-established tool to solve electromagnetic scattering problems. However, the development of efficient and easy to implement pre…
Hybrid coupling of finite element and boundary element methods using Nitsche's method and the Calderon projection
Timo Betcke, Michał Bosy, Erik Burman
In this paper we discuss a hybridised method for FEM-BEM coupling. The coupling from both sides use a Nitsche type approach to couple to the trace variable. This leads to a formula…
Benchmark computations for the polarization tensor of small conducting objects
A. A. S. Amad, P. D. Ledger, T. Betcke +1
The characterisation of small low conducting inclusions in an otherwise uniform background from low-frequency electrical field measurements has important applications in medical im…
Boundary integral formulations for acoustic modelling of high-contrast media
Elwin van 't Wout, Seyyed R. Haqshenas, Pierre Gélat +2
The boundary element method is an efficient algorithm for simulating acoustic propagation through homogeneous objects embedded in free space. The conditioning of the system matrix…
Frequency-robust preconditioning of boundary integral equations for acoustic transmission
Elwin van 't Wout, Seyyed R. Haqshenas, Pierre Gélat +2
The scattering and transmission of harmonic acoustic waves at a penetrable material are commonly modelled by a set of Helmholtz equations. This system of partial differential equat…
Benchmarking preconditioned boundary integral formulations for acoustics
Elwin van 't Wout, Seyyed R. Haqshenas, Pierre Gélat +2
The boundary element method (BEM) is an efficient numerical method for simulating harmonic wave propagation. It uses boundary integral formulations of the Helmholtz equation at the…
High-productivity, high-performance workflow for virus-scale electrostatic simulations with Bempp-Exafmm
Tingyu Wang, Christopher D. Cooper, Timo Betcke +1
Biomolecular electrostatics is key in protein function and the chemical processes affecting it. Implicit-solvent models via the Poisson-Boltzmann (PB) equation provide insights wit…
