Fast BEM Solution for Coupled 3D Electrostatic and Linear Elastic Problems
نویسندگان
چکیده
This paper presents the development of a precorrectedFFT accelerated linear elastic Boundary Element Method solver that can be coupled with existing BEM solvers for electrostatic and Stokes Flow problems. The resulting coupled solvers are mesh consistent—requiring a single mesh for all domains. A number of test cases are evaluated with the linear elastic solver, as well as a coupled electrostatic-structural plate bending problem. performance of the accelerated solver is very good, approaching O(N logN) for CPU time and memory expense for most test cases. Accuracy is reasonable, but for some problems highly refined meshes may be required to achieve this.

A dual BIE approach for large-scale modelling of 3-D electrostatic problems with the fast multipole boundary element method
A dual boundary integral equation (BIE) formulation is presented for the analysis of general 3-D electrostatic problems, especially those involving thin structures. This dual BIE formulation uses a linear combination of the conventional BIE and hypersingular BIE on the entire boundary of a problem domain. Similar to crack problems in elasticity, the conventional BIE degenerates when the field o...
متن کاملFast multipole method applied to elastostatic BEM-FEM coupling
BEM-FEM coupling is desirable for three-dimensional problems involving specific features such as (i) large or unbounded media with linear constitutive properties, (ii) cracks, (iii) critical parts of complex geometry requiring accurate stress analyses. However, for cases with a BEM discretization involving a large number NBEM of degrees of freedom, setting up the BEM contribution to the coupled...

We present simulations of biomolecular electrostatics at a scale not reached before, thanks to both algorithmic and hardware acceleration. The algorithmic acceleration is achieved with the fast multipole method (FMM) in conjunction with a boundary element method (BEM) formulation of the continuum electrostatic model. The hardware acceleration is achieved through graphics processors, GPUs. We de...
