Hi,
I am trying to run a slightly modified version of oodles (added some equations) in parallel and I want to be able to monitor the values of some variables that I am solving for at certain locations in the grid. I see that I have to define a probeLocation file, to start with, besides adding in the createProbes.H the corresponding variables. I guess that at every timestep they values are written in some directory (called "probes"?). Now, I have a couple of questions:
1: probeLocations should consist of (x,y,z) coordinates in my domain or what? i.e something like:

FoamFile
{
version 2.0;
format ascii;

root "";
case "";
instance "";
local "";

class dictionary;
object probeLocations;
}

// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

probeLocations
(
(-4.2426406871192857 -4.2426406871192857 0.00001)
(4.2426406871192857 -4.2426406871192857 0.00001)
(4.2426406871192857 4.2426406871192857 0.00001)
(-4.2426406871192857 4.2426406871192857 0.00001)
);

2: I don't seem to be able to create the probes (sub)directory except by hand a nothing gets written into it. Is there a switch in some dictionary that tells Foam to write at the probes?

I need this to check on something strange that happens in the course of the run (at least for my interests) and I would like to have instantaneous values at some points to compare.

Please help and thanks in advance,
Radu
