Chaitanya, If I understand your question correctly, you should be able to solve your problem by running the Generate Ids filter before writing out the CSV file.

One is of .vtu format and the other is of .xdmf format. However, because I do parallel processing, in the former case, I actually obtain different .vtu files for different processors, a single .pvtu file and a single .pvd file. In the latter case, I obtain a single .xdmf and a .h5 file. Both simulations are 2D, and if you open the spreadsheet format in Paraview, you see something like this: [cid:[email protected]] 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! Thanks in advance! Chaitanya
