Meshless galerkin method 2 d source program
4.0
EFGM calculated source (linear elasticity 2D problem) -EFGM source method (2D linear elastic problems) meshless method (Mesh-less method) meshless method (Mesh-less method) is in numerical calculation the need to generate the grid, but according to some of the coordinates of the point interpolation function constructed arbitrarily distributed discrete control equation, you can easily simulate a variety of flow field of complex shapes. This method can be broadly divided into two categories: one is based on Lagrange method based particle method (Particle method), as smoothed particle hydrodynamics (Smoothed particle hydrodynamics, called SPH) method, and the movement of particles in its development on the basis of half implicit (Moving-particle semi-implicit, referred to as MPS) method; the other is based on Euler method without lattice method (Gridless methods), if there is no grid Euler / N-S algorithm (Gridless Euler / Navier-Stokes solution algorithm) and free Galerkin method (E

Galerkin-type meshless method MATLAB procedures meshless method based on the point of approximation, can be completely or partially eliminate the grid, the grid does not require the initial division and reconstruction, not only can guarantee the accuracy of the calculation, and can greatly reduce the difficulty of calculation. However, due to the current meshless approximation there is no analytic expression in general, and mostly based on the Galerkin principle, the calculation of a large volume, it is necessary to go beyond the traditional finite element method In addition, the meshless approximation are fitted, so displacement of the border more difficult to deal with, the use of Lagrange law.
