-Other field representations are available, selected in the menu '''[Fields]''' at the top of the GUI. For instance the option 'u' provides a (false) color map of the x wise velocity component. A contour plot can be obtained instead of a color map by selecting the option 'contour' in the menu '''[ListContour]''' in the frame''' [Scalar] '''. Then select the contour interval, for instance 0.5. The result is shown in the following figure.  <doc145|center>

 To get the vorticity field, 'vort' , and other spatial derivatives, you need to come back to the GUI CIV, select the check boxes '''[FIX1] ''' and  '''[PATCH1] ''' , and press '''[RUN]'''. This will produce an interpolated velocity field and their spatial derivatives in the same netcdf file.  After this operation vorticity can be visualized in the GUI  '''uvmat''', selecting the option  '''[vort] ''' in the popup  menu '''[Fields]'''. The color code can be adjusted by the edit box '''[MinA] ''' (saturated blue color below this value) and '''[MaxA]''' (saturated red color beyond this value).
