Hi everyone,

I have been using probes and probeLocations for some time and getting the data into a csv file using pyFoam:

Code:
pyFoamTimelinePlot.py --fields=<field> --basic-mode=lines --csv-file=<field>.csv postProcessing/
And had no issues with it for a while. I attempted to do the same as I usually do (run foamCalc on various fields, then run probeLocations, and then run pyFoamTimelinePlot.py) but am not getting an error from PyFoamTimelinePlot that the files in postProcessing/probes are the wrong format. I've attached my sampleDict file as a txt file and an example of one of my files created after running the probeLocation utility. I noticed that in a previous example that worked, I didn't have the lines at the top listing the probe numbers and locations.

I have no idea why I would have it this time... am totally stumped on this!!

I tried to work around it by using the sample utility but this creates a new directory for every time step. How would I combine that data from all of the time steps into one file so I can plot over time?

I would really appreciate any help on using these utilities, totally confused because I did have this all working well.

Hi there @gned,

Which version of openfoam are you using?

I discovered that the format that the data for probeLocations is written changes in (I think) version 2.4.0, which makes pyFoamTimelinePlot not work. I resolved this by simply using the source code from an older version (OF 2.3.0) to write the data using probeLocations and then pyFoamTimeLinePlot worked again!

A little bit of a cheating fix, but it worked for me

Hope that helps,
Ariel
