A meshfree-based local Galerkin method with condensation of degree of freedom
Condensation technique of degree of freedom is first proposed to improve the computational efficiency of meshfree method with Galerkin weak form. The local discrete equation is established by using moving kriging interpolation based on cells with arbitrary shape. Computational efficiency of present method is improved for nearly 22 times compared with the method proposed by Lei Gu in the numerical example. Numerical example also shows that the present method has good accuracy and convergence.
