Title: A new method to treat essential boundary conditions for the meshless method
Abstract:Since the meshless method has defects in treating displacement boundary conditions and lacks computational efficiency,a simple and practical method is proposed for the treatment of boundary conditions...Since the meshless method has defects in treating displacement boundary conditions and lacks computational efficiency,a simple and practical method is proposed for the treatment of boundary conditions.During the process of constructing trial functions,we modified the weight functions of nodes to make the trial functions pass through nodes with given boundary conditions.Displacement boundary condition treatment methods in Finite Element Method was used to satisfied the boundary condition previously.The method presented here reduces computational effort and can solve problems of displacement boundary conditions and finite element coupling that the meshless method can not deal with.The moving least square(MLS) method improves the accuracy and effectiveness of this method.Read More
