Abstract : The authors investigate the numerical generation of three dimensional finite difference grids using a segmentation approach and biharmonics. Their approach is to construct a grid system in a region omega as a union of subgrids which are determined individually but which join smoothly at the boundaries between subregions. To compute the grid on a subregion omega sub s by solving a linear fourth order system of elliptic equations.
