export single streamline data with the corresponding field in it

Please login with a confirmed email address before reporting spam

Hi all, I am looking for a way to export the electric field along a single chosen streamline (and preferably to get both on the the same file). I can generate a single streamline on its own and the electric field map (for the entire geometry) on its own but didn't see anyway to get them both together. Even just getting the field data for that streamline on its own will be a huge help.

Do you want to export or import the streamline?

If you want to export plot data for a streamline with associated expressions evaluated on the streamline then you can add a Color Expression or Export Expressions subnode to the streamline. The latter subnode doesn't affect what's plotted, but it contributes data when you export plot data.
