$SpaceRegion

Format

$SpaceRegion
 xL    xR                
 yL    yR
 zL    zR                // where all are floating points. Unit: meter.

The function defines the simulated space. x_L / y_L / z_L is the position of the first point in x / y / z-axis, and x_R / y_R / z_R is the position of the last point in x / y / z-axis.
The unit is meter (m).

Example

$SpaceRegion
 0.0    200e-6
 0.0    200e-6
 0.0    200e-6

This means the space region is from (0, 0, 0) to (200, 200, 200) (μm).
