Description The grid density requirements generally vary from problem to problem, hence interactive control over grid generation is required. While multi-block grids can be used to control the grid density globally, interactive mechanisms are required to carry out grid density manipulations locally. If we are able to accommodate an unequal number of grid points on opposite edges in a block, then this can be achieved with minimum manipulations in the neighbouring blocks. This also results in savings on the number of grid points. In this paper an algorithm for this is presented. A mechanism to control distribution of boundary points and the orientation of grid lines within a block, using simple algebraic expressions is also presented.
