    4949The previously used linear interpolation does not provide field derivatives. For that purpose, we proceed as previouisly but use the option '''[!ProjMode]=''''interp_tps' for the projection plane in '''set_object'''. To reach this GUI using the same projection object as before just select the check box '''edit''' to open the GUI '''set_object'''. Change the option '''[!ProjMode]''' and click on '''[REFRESH]'''.

    51 In the GUI '''series''', select simultaneously the fields 'vec(U,V)', 'curl(U,V)' and 'div(U,V)' to get the vorticity and divergence in addition to velocity. The calculation is significantly longer that for 'interp_lin', so in the demo we use a resolution DX=DY=0.2 cm for the projection plane (instead of 0.1 cm).
