Documentation

You cannot load an arbitrary data set. Its fixed to the block data. On the left you can select die background to be displayed (presure/vorticity). There are also two checkboxes toggling arrow plot / stream line display. Youn can choose integration method for stream line generation together with the dsep parameter. You first have to push the generate button in order to display the stream lines. Toggling interactive, you can click on the image and streamlines are added with die approprate method and dsep

Arrow plot

Runge-Kutta integration; dsep=10 pixel

Euler integration, dsep = 10 pixel

Euler integration; dsep = 20 pixel

Runge-Kutta integration; dsep = 20 pixel
