Meshfree finite differences for vector Poisson and pressure Poisson equations with electric boundary conditions

, 2013
We demonstrate how meshfree finite difference methods can be applied to solve vector Poisson problems with electric boundary conditions. In these, the tangential velocity and the incompressibility of the vector field are prescribed at the boundary.

Brownian dynamics of rigid particles in an incompressible fluctuating fluid by a meshfree method

, 2015
A meshfree Lagrangian method for the fluctuating hydrodynamic equations (FHEs) with fluid-structure interactions is presented. Brownian motion of the particle is investigated by direct numerical simulation of the fluctuating hydrodynamic equations.

GIZMO: A New Class of Accurate, Mesh-Free Hydrodynamic Simulation Methods [PDF]

, 2015
We present two new Lagrangian methods for hydrodynamics, in a systematic comparison with moving-mesh, SPH, and stationary (non-moving) grid methods. The new methods are designed to simultaneously capture advantages of both smoothed-particle hydrodynamics

Symmetric boundary knot method

, 2002
The boundary knot method (BKM) is a recent boundary-type radial basis function (RBF) collocation scheme for general PDEs. Like the method of fundamental solution (MFS), the RBF is employed to approximate the inhomogeneous terms via the dual reciprocity ...
