Limits of the grid :
         * **imin** =0 (always) : index of the first column
         * **jmin** =0 (always) : index of the first row
         * **imax** : index of the last column
         * **jmax** : index of the last row
         * **kmax** : number of layers
                 * **k=1 bottom layer**
                 * **k=kmax surface layer**
