Hi OpenFOAMER,
I want to sample data from a 3D box out of the original full domain. I tried the sample array of the sample utility, here comes the input in sampleDict:

sets
(

arrayA1
{
// Sample 'pointsDensity' points in a box with origin at 'origin'
// plus the vector 'spanBox'
type array;
axis xyz;
coordinateSystem
{
e1 (1 0 0);
e2 (0 1 0);
origin ( 0 0 0 );
}

origin ( 0 0 0 );
coordinateRotation
{
type axesRotation;
e1 (1 0 0);
e2 (0 1 0);

}

pointsDensity (40 100 10);
spanBox (0.1 0.1 0.01);

}
);

The problems is that, I can get the intended 3D box data, but without the data at the boundary I specified. So my question is if any one hows how to sample the 3D-box data with also with the boundary point? Or if any have any better idea of sampling a 3D-box data with boundary point data?

Thanks very much
