Hi all

I am simulating the electric field from en earthrod placed in ground in 3D. So far I've gotten fine contour and multislice plots of how the electric field decreases in the ground away from the rod. I would like to know the voltage in some certain points (one, five, etc meters) away from the rod and am struggling with how to do so.
Is there any easy way to do this, for example by setting a point by the coordinates (y=0, x=5, z=0)?

Thanks!

Thomas

Hello Thomas,
You can achieve this is several ways, such as creating a dataset of the Cut Point 3D type, and then using it in Derived Values.

For many more tips on post-processing with COMSOL, see these booklets:

Thanks Jeff, I'll give that a try!
