=='''Format'''==
 $Deltaxyz
  ''dx''
  ''dy''
  ''dz''                <font color=green>// where ''dx, dy, and dz'' are real numbers.</font>

<font size=3>The function defines the mesh size in x, y, and z directions.<br><br>

<font size=3 color=red>
'''NOTE 1'''<font color=black>: The priority of this function is above the function -- [[$CellNumber]], ''i.e.'', the program will abandons [[$CellNumber]] while using [[$Deltaxyz]].</font><br>
'''NOTE 2'''<font color=black>: When using this function, since the position of the last grid can not be beyond the boundary we set, the position of last point may not be same as the function -- [[$SpaceRegion]]. (also due to the equivalent array size in 6 field.)
</font></font>

=='''Example'''==
 $Deltaxyz
  1.0e-8
  1.0e-8
  1.0e-8

Thus, in each direction, the distance between two neighbor points is 1.0e-8 (m).
