Hello,
I have a model which simulates the electric field of a device and traces particles in this field.
How can I plot the electric field (with vectors) along the particle's trajectory?
Thank you
DAniel

Hi Daniel, there isn't a particularly convenient way of doing this in V4.4, but you can use the Comet tail option for the Point type to visualize a vector quantity. You can see this in the attached model and animation.

In our next release, it will be possible to set the Point type to Arrow, which will allow much more convenient visualization of vector fields along particle trajectories.
