Abstract
An application of interactive Virtual Reality techniques to the manual repair of automatically generated 3D computational grids is described. Grid quality is assessed by a range of measures and bad elements which fail these checks are highlighted. The user immersively enters the grid and uses navigational and manipulative techniques to correct the grid and confirm its validity. Pointers to future extensions of these techniques are given.
