It is too cumbersome to extract and plot the pathlines for all of the thousands of particles that can be generated during a PT simulation. The PT Pathline Extraction utility allows you to extact the pathlines for specific particles if you have saved the intermediate locations in the Storing of Results (V1 p. 335) dialog.
In the top level of this data tree item, you can specify any number of different pathline extractions. These will be saved from simulation to simulation, allowing you to re-run the extraction for different scenarios.
The buttons at the bottom, allow you to run the selected extraction or all of the specfied extractions.
Extraction Properties
To extract a particle pathline you need a Particle ID. These can only be found after the simulation by evaluating the PT output. For example, you can find the particle ID by extracting the particle start locations that end in a specific well and then finding the ID numbers of the particles that you want in the shape file that was created.
