    6565== Example of an intense vortex ==
    66 With the GUI '''uvmat''' open an image in '/UVMAT_DEMO04_PIVchallenge_2001A/images' taken from PIV challenge ([http://www.pivchallenge.org/] see website). A short description of the experimental conditions is given in the file 'readme.txt' in the folder of the images. It is said that the field of view is 170 x140 mm, so that, since the image size is 1280x1024 px, the scale is 7.4 px/cm. but no time Dt **. The flow is the vortex behind a wing with poor particle seeding in the core.

    6868From '''uvmat''' select '''[Run/PIV]''' so the GUI '''civ_input''' pops up. With the option''' [!ImportParam]''', import the parameters from the file 'Images.ref.civ/0_XML/A_1_1.xml' and '''[RUN]''' the civ calculation. The result should look like the reference result 'Image.ref.civ/A_1_1-2.nc'. As expected form the dark spot at the vortex centre, the core is not properly resolved in civ1. The result is improved in civ2.
