The lattice Boltzmann method is a microscopic-based approach for solving the fluid flow problems at the macroscopic scales. The presently popular method uses regularly spaced lattices and cannot handle curved boundaries with desirable flexibility. To circumvent such difficulties, a finite difference

## Abstract Although unconditionally stable (US), the accuracy of ADIโFDTD is not so high as that of conventional FDTD. In this paper, a highโorder USโFDTD based on the weighted finiteโdifference method is presented. A strict analysis of stability shows that it is unconditionally stable. And, more
## Abstract The elementโfree Galerkin method (EFG) and the natural element method (NEM) are two well known and widely used meshless methods. Whereas the EFG method can represent moving boundaries like cracks only by modifying the weighting functions the NEM requires an adaptation of the nodal setโu
