Hello Abhijeet,

input contains the cuboid number and then the lattice coordinates, so, effectively, it is an array of length 3. For technical reasons, output also needs to have length 3 (dimension+1).

If you want to get processable data (in contrast to debugging purposes), you also need communication on the block overlaps. Therefore, the usage of BlockReduction and physical functors is strongly recommended, because it executes these steps for you.
