I am a new user to Nek5000 and I have been experimenting with DNS of turbulent channel flows using the turbchannel example. I believe I have gotten a basic case running. Now I would like to be able to open/edit the output files to be used as starting points
for future simulations. The problem I am having is in understanding how to go about modifying the resultant files (.f000*), does this have to be done through the postprocessor? If so, can someone point me in the right direction as I am quite confused.</div>
