The surface boundary conditions are imposed by reflected points. A cloud of nodes in the vicinity of the surface is used to get a weighted average of the flow properties via a gridless least-squares technique. If the displacement of the moving surface from the original position is typically small, a small-perturbation boundary condition method can be used. To ensure computational efficiency, multigrid solution is made via a framework of embedded grids for local grid refinement. Computations of airfoil wing and wing-body test cases show the practical usefulness of the embedded Cartesian grids with the small-perturbation boundary conditions approach. © 2010 Elsevier Inc.||Source Title:||Journal of Computational Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/115098||ISSN:||00219991||DOI:||10.1016/j.jcp.2010.01.014|
