RE left-handed grid, you've put you ijk origin in the wrong place. Shift it over to the other side of the mesh. If you're using a polar mesh, just rotate the circular plane around the other way.

To close the loop, you need to define some cyclic boundary conditions at the extents where the loop closes.
