Hey John,

You can use the typical i/o functions of C to write data to file, such as fprintf (for a text file, easily opened in excel/matlab/...) or fwrite (for a binary file, which is more storage friendly but takes more effort to read, use this if storage is critical)

I would suggest to use txt commands.

/surface/point-surface to specify your sampling point.
/solve/monitors/surface/set-monitor to start writing your sampled quantity to file this will generate an .out file wish you can convert to txt file and read into excel.

Good luck!
