2D simulation: boundary plot (line graph) prevent interpolation

Hi,
in my 2D simulation I want to determine the electric field strength at the curved boundary between two domains. The simulation works without any problems. There are some undefined oscillations of the absolute value though.
In my opinion this could be caused by the interpolation of several mesh points in the vicinity of the mesh points on the boundary.
1. Can I extract the values of the mesh points that solely lie on the boundary and use them for my line graph, without any interpolation or averaging?
2. Is there a chance that I can make a curved 2D cutline, parallel to my boundary?
Best regards
Andreas

Hi
For the plot check your advanced plot inerpolation / smooting tab settings (you might need to turn on "preferences show advanced"
Then why not make an internal boundary by copy/scaling your first domain, then you can pick this internal boundary for your plot line and data extraction.
Anyhow in ACDC avoid sharp edges as the flux values are undefined on the vertex. You may fillet off most sharp edges

Good luck
