<p class="MsoNormal" style="margin-left:.5in">I need to do some post processing on the solution vectors 'u' and 'v'. You may also refer to them as 'ux' and 'uy' OR "f_18_1" and "f_18_2". Therefore, I need to import it in MATLAB. To do that, in ParaView, I first
go to menu >> save data >> save file in CSV format for all points. The csv file I am looking at gives me 6 columns - Coordinate X, Y, Z, Solution ux, uy, uz. Here Z and uz are zero vectors. How can I also get the node number for the given node coordinates,
and how can I get the elemental nodal connectivity? Any help is greatly appreciated!<o:p></o:p></p>
