Hi all,

I am using the functionality in the GUI related to monitoring points to observe the evolution of the solution over time at certain points. I notice that, when opening the probes_coords.csv file, the coordinates that I entered were slightly modified. My question is, do they automatically change to the position of the nearest cell center? Is there a way to configure it to maintain the entered position using some type of interpolation?

Hello,

Yes, you can set part of this behavior in the GUI ("one probe per cell"), and can have finer grained controls in user-defined functions.
Check the Doxygen (html) documentation for cs_probe_set_t. The default behavior will also depend on whether the mesh is fixed (where we snap coordinates to cell centers) or moving/deformable. The distance between requested probe locations and matching cell centers is also summarized in run_solver.lig.

Regards,

Yvan
