A parallel fast multipole method for a space-time boundary element method for the heat equation
Raphael Watschinger, Michal Merta, Günther Of +1
We present a novel approach to the parallelization of the parabolic fast multipole method for a space-time boundary element method for the heat equation. We exploit the special tem…
An integration by parts formula for the bilinear form of the hypersingular boundary integral operator for the transient heat equation in three spatial dimensions
Raphael Watschinger, Günther Of
While an integration by parts formula for the bilinear form of the hypersingular boundary integral operator for the transient heat equation in three spatial dimensions is available…
Semi-analytic integration for a parallel space-time boundary element method modeling the heat equation
Jan Zapletal, Raphael Watschinger, Günther Of +1
The presented paper concentrates on the boundary element method (BEM) for the heat equation in three spatial dimensions. In particular, we deal with tensor product space-time meshe…
Complexity Analysis of a Fast Directional Matrix-Vector Multiplication
Günther Of, Raphael Watschinger
We consider a fast, data-sparse directional method to realize matrix-vector products related to point evaluations of the Helmholtz kernel. The method is based on a hierarchical par…
A parallel solver for a preconditioned space-time boundary element method for the heat equation
Stefan Dohr, Michal Merta, Günther Of +2
We describe a parallel solver for the discretized weakly singular space-time boundary integral equation of the spatially two-dimensional heat equation. The global space-time nature…
A non-symmetric coupling of the finite volume method and the boundary element method
Christoph Erath, Günther Of, Francisco-Javier Sayas
As model problem we consider the prototype for flow and transport of a concentration in porous media in an interior domain and couple it with a diffusion process in the correspondi…
