Dear All, I run a FEM simulation in FEniCS to obtain two output files. 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: 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
