$SourcePosition
 pt1    pt2    pt3    pt4    pt5    pt6                // all are floating points.

Define the source area.

If it is not any node at the pt, the program will find the nearest point/face as the source.

 When the type of source in $SourceType is 
 1~4: you only need pt1 to define the position, axis (in $SourceType) decides which surface is used.
 11~14: similar to 1~4, but dir (in $SourceType) decides which direction the wave propagates.
 21~24: pt1~6 are x-, x+, y-, y+, z-, and z+. This tells the program where the total field is.
 31~34: pt1~6 are x-, x+, y-, y+, z-, and z+. (not finished)
 51~64: pt2,4,6 are x, y, and z. Define which point is the source.

Example

$SourcePosition
 700e-9    0    0    0    0    0
