Thanks Bojan. I suppose that would work. Problem arises, however, when the actual application numbering matters and you have to preserve it somehow. One example, is where you have a library that is currently sequential and a lot of functionality is directly based on the data structure used for the grid. For example when computing derivatives or performing interpolation and so on.</blockquote>
