How to plot electric field along a broken line

Hi,

I'm hoping someone can advise me on this problem.

I've recently been using Comsol 4.2 to get the electric field. The geometry I am using has a sawtooth boundary. And I am trying to get the electric field along the sawtooth. But I got trouble when I tried to define the Data Sets. It seems that "Cut Line 2D" can only be used for a straight line. However, what I want is a broken line.

Any advice?

Thanks in advance

Hi

what about selecting the boundary and plotting either along the arc ("s"), or along a coordinate x,y,z ?

Good luck

Hello Ivar,

Sorry, I did not get it. Could you explain it a little bit more.

Hi

you said you ave already a boundary, then "my way" would be to make a "Line plot" select the sagged boundary and plot the electric filed.
Optionally you can replace the plot "x" axis (by default the "arc" length), by an expression such as "x" or "y" to use a coordinate
