    44 Create a projection grid in phys coordinates. For that purpose, open a velocity field of Dalsa1.sback.civ_bulk with uvmat, displayed in phys coordinates. Use the upper bar menu option '''Projection object/plane'''. Then in the GUI '''set_object''', choose the option '''[!ProjMode]=''''interp_lin'. Choose a mesh 0.1 cm in each direction, ranging from 0 to 58.8 in x and 0 to 55 in y. Press '''[REFRESH]''' to see the result of projection in the GUI '''view_field'''. Check the option '''nb_vec/4''' in '''view_field''' to reduce the number of vectors displayed on the plot.

    46 Now in '''series''' open the PIV file ''Dalsa1.sback.civ_bulk'' as input. Then append the second file ''Dalsa1.sback.civ_plume'' using the menu bar selection '''!Open/Browse append...'''. Select '''[[wiki:ActionName !ActionName]]'''= 'merge_proj'. Set '''!FieldTransform''' to 'phys', and select the check box '''Projection Object'''. The plane for projection is then incorporated in '''series'''. It is also advised to introduce masks in the interpolation process so that each field is interpolated in its range of validity. This is done by selecting the check box '''Mask'''. Use the browser to fill the table of masks, in accordance with the table of input file series. Press '''[RUN]''' to launch the calculation. Then press '''[STATUS]''' to see the result with '''uvmat'''.
