Efficiently Draw 2D Cut Lines in COMSOL: Step-by-Step Solution Guide

[iza888]

I am soooo stuck with how to draw 2D cut lines from (b) in this solution set. I know its probably something really simple but its driving me crazy. I really don't know how to define the zeta cut lines and make a sketch as generated in the attachment. If someone could please give me some more detailed solution on how to complete step b I would really appreciate it.

I am just a beginner to COMSOL and I am really struggling with this - I have a test on Monday and I know that very similar concepts will be on the test. I am really panicking currently because I have been trying to figure this out for hours and I still can't do it ;(

Please help me.

Thank you a lot!

The best way to approach this problem is to first understand the concept of the zeta cut lines. Zeta cut lines are used to analyze the solution set of a differential equation by cutting the plane along a certain line. This line is called the zeta cut line and it is used to observe how the solution changes over that line. In your specific case, you need to draw the zeta cut lines on the solution set plotted in (b). To do this, you will need to determine the zeta values that you want to plot. The zeta values correspond to the coordinates of the points along the zeta cut line. You can choose to plot zeta values that are in the range of the solution set, or any other range that you want to analyze. Once you have determined the zeta values, you can begin to draw the zeta cut lines. To do this, take a pencil and ruler and draw a line from one of the zeta values to the next. Repeat this until all of the zeta values have been connected by a line, forming the zeta cut line. You can then draw the same line on the solution set (b) and you will see the zeta cut lines clearly. By following this approach, you should be able to draw the 2D cut lines from (b) in the solution set. Good luck!
