Format
$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
