Field Convert Tecplot Data Format
Hello, I would like to import the output of Nektar++ to numpy array to do some post processing. I was thinking to convert the output to tecplot readable files and then import the results in numpy array format. The problem I'm facing is that the output generated by FieldConvert seems not to be in the classical DATAPACKING=POINT that makes the import straightforward. Do you know if there is any possibility to convert the output in that format or do you have any suggestion to solve my issue? Many Thanks and have a nice weekend! Regards, Riccardo
Hi Riccardo, You could try the Tecplot (or Paraview) Python API. Tecplot has a very good documentation of how to set it up. You would than do something like: import tecplot tecplot.new_layout() dataset=tecplot.data.load_tecplot(filename) At this point you would have the dataset and could do what you want.

Hi Riccardo, in case you are only interested in the plain point data without connectivity information, you can also use FieldConvert to export the data to .csv files at the quadrature points directly: FieldConvert-g case.xml case.fld case.csv The resulting csv files are already formatted to be read by numpy, e.g. np.genfromtxt(fname=fn, names=True, delimiter=',' ) Cheers, Kilian Am Freitag, 20.
