Efficient FMM accelerated vortex methods in three dimensions via the Lamb-Helmholtz decomposition
Vortex-element methods are often used to efficiently simulate incompressible flows using Lagrangian techniques. Use of the FMM (Fast Multipole Method) allows considerable speed up of both velocity evaluation and vorticity evolution terms in these methods. Both equations require field evaluation of constrained (divergence free) vector valued quantities (velocity, vorticity) and cross terms from ...
متن کاملAn Implementation of Low-Frequency Fast Multipole BIEM for Helmholtz’ Equation on GPU
Acceleration of the fast multipole method (FMM), which is the fast and approximate algorithm to compute the pairwise interactions among many bodies, with graphics processing units (GPUs) has been investigated for the last couple of years. In view of the type of kernel functions, the non-oscillatory kernels (especially, the Laplace kernel) were studied by many researchers (e.g. Gumerov), and the...
متن کاملA broadband fast multipole accelerated boundary element method for the three dimensional Helmholtz equation.
The development of a fast multipole method (FMM) accelerated iterative solution of the boundary element method (BEM) for the Helmholtz equations in three dimensions is described. The FMM for the Helmholtz equation is significantly different for problems with low and high kD (where k is the wavenumber and D the domain size), and for large problems the method must be switched between levels of th...
متن کاملA Free-Space Adaptive FMM-Based PDE Solver in Three Dimensions
We present a kernel-independent, adaptive fast multipole method (FMM) of arbitrary order accuracy for solving elliptic PDEs in three dimensions with radiation and periodic boundary conditions. The algorithm requires only the ability to evaluate the Green’s function for the governing equation and a representation of the source distribution (the right-hand side) that can be evaluated at arbitrary...
متن کاملNumerical Study of Three - Dimensional Flowusing Fast Parallel Particle Algorithms
Numerical studies of turbulent ows have always been prone to crude approximations due to the limitations in computing power. With the advent of supercomputers, new turbulence models and fast particle algorithms, more highly resolved models can now be computed. Vortex Methods are grid-free and so avoid a number of shortcomings of gridbased methods for solving turbulent uid ow equations; these in...
