Sir,
In creating periodic zones, it is asking for X offset and Y offset values. Exactly what it is asking for these values?

If auto is not on, you must manually input the x,y, and z translation vector that defines the periodicity. In 1D, that is the length of the periodic domain. In general, periodicity does not have to be restricted to along only the x-axis, y-axis, or z-axis and can occur along arbitrary translations vectors, x,y,z.
