I understand simple grading is the ratio between the size of the end cell and the size of initial cell.
How about the cell size in between, what kind of changes they follow to reach the final cell?
Like constant changes?
For instane, the first cell is size 10 and the last cell is size 5, the middle cells will have a size 10-dx*(N-1) ? where the dx is the constant changes between cells, N is the number of cells in that direction.

This is how i understand it, not sure if thats right.

I am writing a small code to output the cell ID by just inputting the x,y coordinates, however i realised that it only work fine for uniform distributed mesh, not the one with gradings. Hence i came out with this question. Any one have any suggestions? (Or if anyone has faster way to output cell ID (in paraview) and dont mind share with me)

Many Thanks.
