I am currently working on the interface, it should be available soon (a few weeks). But, there is formula available in the current release. Under Formulas > Grids > Greate 2D/3D Flow Trajectory. Load your dataset first, and then in the Field Selector panel, select Formulas > Grids > Greate 3D Flow Trajectory, when a new window popup, selct u,v, w, and a scalar variable, and the last selection is to select the same scalar variable, but you need to specify the level, the initial time and region. If your dataset is big, the calculation will take a while. When the new interface is available in a few weeks, it will be easier.
