$Deltaxyz

Format

$Deltaxyz
 dx
 dy
 dz                // where dx, dy, and dz are real numbers.

The function defines the mesh size in x, y, and z directions.

NOTE 1: The priority of this function is above the function -- $CellNumber, i.e., the program will abandons $CellNumber while using $Deltaxyz.
NOTE 2: 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.)

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).
