hi
i'm trying to get the pressure along a curved pipe wall.
for example if i have 3 points defining the curve (as in blockMeshDict - edge -arc setup) & when i try the simple sampleDict as below i get an error.
i've searched around but not found any real help.
works fine with straight lines.
is there a better way to get pressure, etc along a curved wall for plotting in excel.
please help.

FoamFile
{
version 2.0;
format ascii;
class dictionary;
location system;
object sampleDict;
}

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

setFormat xmgr;

surfaceFormat vtk;

interpolationScheme cellPoint;

fields
(
p
);

sets
(
section_curve1
{
type curve;
axis distance;

points ((-1.0 0.0 0.0)
(-0.71 -0.71 0.0)
(0.00 1.0 0.0));
}

);

surfaces
(
);

One of the options with the sample utility is to specify a series of points explicitly. This is the 'cloud' option. You can then extract values from each of your solutions at exactly those points using sample.
