Meshless Regular Hybrid Boundary Node Method

Computer Modeling in Engineering & Sciences, 2001
The Meshless Local Boundary Integral Equation (MLBIE) method is a truly meshless one as it does not need a 'finite element or boundary element mesh', either for variable interpolation or for 'energy' integration. The Boundary Node Method (BNM) further reduces the dimensionality of the problem by one, i.e.

Kinetic Meshless Method

, 2003
We propose a new method called the Kinetic Meshless Method (KMM), for the solution of time-dependent conservation laws that can be derived from a Boltzmann-type equation by taking suitable moments. An important characteristic of this method is its grid-free nature; it is able to use any type of grid or combination of grids, or even some distribution of

A Novel Third Order Numerical Method for Solving Volterra Integro-Differential Equations

, 2016
In this paper we introduce a numerical method for solving nonlinear Volterra integro-differential equations. In the first step, we apply implicit trapezium rule to discretize the integral in given equation.

Taylor-SPH meshless method

, 2015
In this work, we present the Taylor-SPH meshfree method for dynamic problem. The PDEs are written in terms of stress and velocity. A corrected Lagrangian kernel is employed for spatial discretization and two different sets of particles are used for time discretization.
