Read this few paragraphs to get an idea of the input-output procedure.
The program is launched by clicking on the icon on the download page. If you use JPIV the first time, a settings file (jpiv_settings.ser) is created in your home directory. The main-frame of the program contains three sub-windows. The "Settings" window on the left side gives you concise access to all properties. The "Files" window on the right maintains an interactive list of the image and vector files you are currently working with. The "Cmd" window is used for system output and scripting.
The user interface just after startup.
The procedure for PIV image evaluation - and other operations - in general:
1. Load some image file names into the "Files" frame.
2. Modify the properties on the panels in the "Settings" frame.
3. In the "Files" frame, select the files you want to process.
4. Start the processing by selecting a command from the drop down menus.
5. Display the result by double clicking on a filename in the "Files" window.
Example:
Use the File-Choose menu item or the corresponding toolbar icon to choose some image files. If you do not have PIV images at hand, you will find some on the download page.
Expand the general parameters tab and edit the parameters according to your images.
Edit the interrogation window parameters.
Select the image files you want to process.
From the PIV drop down menu, choose the command run PIV image analysis to start the image evaluation. You are asked about a file name for the result. When the evaluation is finished, the result vector files are appended to the file list. Select the result vector files for post-processing.
Choose the batch filtering script from the Script menu. Alternatively, you can apply the filters directly via the Vector drop down menu.
A dialog appears. Select the filters you want to apply and how often they should be repeated. Again, you are asked about a file name for the results.
Analog to the operations above, select the filtered result files and apply the drop down command Vector - normal vorticity to calculate the vorticity. Finally, double click the latest result files to show them on screen.
