After calculating path lines (flow calculation) or streamlines (data export), the following input block appears when the corresponding data type is selected. This is identical for streamlines and trajectories. However, if the "Save extended velocity field for path line postprocessing" checkbox was activated for a transient flow calculation and the data export of path lines was subsequently carried out, the trajectories from the post-processing are offered as result data:

In addition to the graphic properties of colour, line type and line width, you can select whether only the lines are displayed (without markers) or whether markers (+) are placed on these lines.

The markers can be set either according to a distance [m] to be entered or a time span. The time span can be specified in seconds, minutes, hours, days, months or years (batch command BAHN or STRO).
