Hello， I am using the command DMDAGetElements to get the number of elements in the grid and the index of the points within each element, but I found a problem that the accuracy of this command depends on the number of x, y, z direction cels I then create. Take \src\ksp\ksp\tutorials\71 as an example, when the values of cells are 4,3,2. using two processes to complete -dim 3 -cells 4,3,2 -pde_type Poisson -use_global, here the index of the points in the elements in each process will have problems, the given local index corresponds to the coordinates of the points in the local to see that the cell will have problems. Take my results as an example, process 1 gives the local indices of the first element's vertices (0 1 5 4 16 17 21 20). But the corresponding coordinates are 0 1 5 4 16 17 21 20 x 0 2 0 8 2 4 2 0 y 0 0 2 0 6 6 0 0 z 0 0 0 0 0 0 2 2 You can see that this is not a correct element
