Hello all,
I have a transient simulation for 1000 timesteps and timestep size of 0.0001 s .
Now I want to get the average of a field variable (lets say pressure) over flow time on a plane. (please note the attached figure.
I have the data files autosaved in every 50 timesteps but they only have the reports for mass flow rate.
Besides when I export the final case and data to CDAT and want to add more timesteps there is no option since there is just one .trn file.
Is there any way I can plot such contour that shows the time-average of a flow variable on a geometrical feature over time?
I wonder if anyone can guide me on that.
I have heard of data sampling but there are problems if I want to follow that path:

1) This solution is the continuation of a previous steady.
2) I did a mistake and did not enable data sampling option at the start of calculation; The simulation takes so long so I guess there should be a easier way...
Thanks in advance for your help
