 From '''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.
