Adaptivity via mesh movement with three-dimensional block-structured grids
- Defence Research Agency, Farnborough, Hants (United Kingdom)
The method described here is one in which grid nodes are redistributed so that they are attracted towards regions of high solution activity. The major difficulty in attempting this arises from the degree of grid smoothness and orthogonality required by the flow solver. These requirements are met by suitable choice of grid equations, to be satisfied by the adapted grid, and by the inclusion of certain source terms, for added control in regions where grid movement is limited by the local geometry. The method has been coded for multiblock grids, so that complex configurations may be treated. It is demonstrated here for inviscid supercritical flow with two test cases: an ONERA M6 wing with a rounded tip, and a forward-swept wing/fuselage configuration (M151).
