Dear all,


my last post got lost I'll retry...
I created a plain txt file containing the coordinates along a curve. So something like
Code:
x1 y1 z1
x2 y2 z2
x3 y3 z3
....
I now want to extract the field values at those points. I found the postProcessing utility internalcloud, which looks promising. My below code works fine, However I could not figure out how to read the plain ASCII file into the dictionary, instead of specifying points manually. Does anyone has a hint how to do that?


Kind regards
Jerzy
PS: I do know how to read files with C++, but could not figure out how to combine it with the dictonary. Sorry if the answer is trivial, Im quite new to OpenFOAM


Code:
pressure_plot
{
    type            sets;
    libs            ("libsampling.so");

    interpolationScheme cellPoint;
    setFormat       raw;

    writeControl    runTime;
    writeInterval    0.001;

    fields  (p);
    points
    (
    (0.0936413556337 0.0815078690648 0.0702539756894)
    ......

    );

    sets
    (
    cloud
    {
        type    cloud;
        axis    xyz;
        points  $points;
    }
    );
}
