Grid Definition

The grid can be easily specified by the user. Consider the following example:
1.0 5000 10.0
This command will assign 5000 points linearly dispersed between the 1.0um and 10.0um.

Consider another example:
0.0 1000 3.0 3000 4.0 1000 7.0
This command will assign 1000 points between 0.0um and 3.0um, 3000 points between 3.0um and 4.0um and 1000 points between 4.0um and 7.0um.
This allows the user to create a non-uniform mesh by assigning more points where the field is expected to be more intense.

All units are in microns.

Important Notes:

• The y-grid can start and end anywhere. For example, you can start at y=-5.0um and end at y= +2.0um.
• However, the x grid must always start at x=0.0um and proceed along the positive axis. This is due to the assumed symmetry of the structure about x=0. Since the x-grid always begins at x=0.0um, you don't have to enter 0.0 as the first number in the grid definition. It is already assumed. This is indicated just left of the text entry box.
