I am having some issues displaying a streamline of the B vector in my solution. I am modelling 2 permanent magnets with a bit of space between them in a 3D magnetostatic simulation. I am able to generate a field report, and view the vector plot, but I am not able to do a streamline. 

No matter what I select, I am not able to do streamline. I select the geometry (I've tried all objects, just one magnet, the vacuum region around it) and go through Field Overlays -> Fields -> B -> B_Vector and get to the following screen. 

I've tried varying the "in volume" selection, plotting on the surface only, but no matter what I do, if streamline is checked, I get the error "Cannot create streamline plot with the selected geometry."

I've tried going through the options as well, but nothing seems to make an impact on the ability to create a streamline plot.

What am I doing wrong? I just cannot figure this out.

Hi, please use the following step to create streamlines:

1) Select Surface (or plane) where streamline points start.
2) Plot B_Vector field overlay (menu: Maxwell 3D >Fields > Fields > B > B_Vector).
3) In the Create Field Plot window, select “Streamline” checkbox.
4) Click “Done” button to view plot.
5) To improve Streamline plot overlay. First, go to Tools > Options > Fields Reporter Options. In the Streamline tab, change Stopping Criteria to 0.01%, and 20 (defaults 5%, and 5).
Then, double-click on the B-field color-key. In the Plots tab, select Streamline Plot. Use the slider on the Seed density spacing.
