Export pressure at node 'i' for each time step
 

Hello everybody,

I have carried out a transient simulation and I'm interested in knowing the value of pressure at a node 'n' at every time step.

If I do File-Export I obtain the desired values but only for the current time step.

I have found that I should do a chart and export it, however, I don't get to do it. I pick "XY - Transient or Sequence" and data series with expression "t", I pick time at x axis and pressure at the y axis. But I obtain a time-time plot!

I will appreciate your help :)

As I think (and as I usually do) you should obtain the value from each timestep file separately (it can be done in journal mode, maybe some post-processors as CFD-Post can also do such work). I hope you saved them.
I usually do similar things during calculation (using execute-command, see links in my answer here) since it allows not to save dat files and perform large calculations on limited disk space.
:)
