Obtaining transient data of a point over time
 

Hi all,

I have a 3D transient problem imported from FLUENT that is working fine with slices and other features but I could not figure out how should I extract pressure data at a point on a surface over time and write it to a text file?
The "Probe to create time series plot" function under tools work well but how could I obtain the data in text? And how should I specify the coordinate instead of using the pointers?
Thanks in advance for the help.

Probe to create time series plot is probably the easiest way to access the data you can use data>Spreadsheet on the derived frame to see the data in a table. Then to write to a file, either File> write data or Tools> Write data as formatted text.

Sadly Probe to create time series plot doesn't have a way to enter a specific location in the GUI. But you can use the macro language to specify the location of the probe.

$!ExtendedCommand
CommandProcessorID = 'Time Series Plot'
Command = 'Command = CreatePlot StrandID = 1 XPos = 0.070113242744 YPos = 0.06046465643 ZPos = 0'

Another option would be writing a pytecplot script using tecplot.data.query.probe_at_position and looping through time.

Thanks for the reply. I have 0 idea how macro and pytecplot works, will try to figure out that part but the "write data as formatted text" works well for me.

A simple recording with scripting> record macro will give you a place to start from. Then if you need any help reach out to support@tecplot.com.
