A grid generation and deformation algorithm was formulated for computing aircraft wings with large deformations. The computational domain was deiscretized, using a hybrid grid that consists of of structured hexahedra around the wing and unstructured triangular prisms in other regions. The mesh was divided in layers, which were topologically identical in the spanwise direction. The mesh algorithm was applied in two steps, such as the spring analogy technique, applied to deform the nodes within a mesh layer. The layers were also deformed, to be perpendicular to the boundaries of the domain and the surface of the wing. The mesh generation algorithm was developed, to satisfy certain requirements, such as allowing large wing deformations without the need to remesh the domain and allowing a better control of the grid size in the boundary layer of the wing.
