Hi all,

I have successfuly followed the "Magnetic Lens" example. Nevertheless, I would like to see the field arrows on the screen but I am not able to do it. Any hints on how to achieve this?. I would like to get the typical drawing like:

hyperphysics.phy-astr.gsu.edu/hbase/magnetic/solenoid.html

Thanks in advance,

Jose.

I'm not sure, but you should try using Streamline.

Hi

have you tried to add the Plot Arrow Volume or Surface (depending on your plot type) ?
I often prefere streamlines on 2D cut surfaces.
Also in certain cases you need to tweak the arrow type and number

Good luck

Thanks for your replies. I have managed to see the lines using streamlines, but I would also like to see them showing the arrows representing the flow direction. I will try with the rest of your comments...
