CFD Online Discussion Forums - unstructured sampling in function objects

Hi,

I have a cutting plane in my function objects to export data for short times. However when I'm opening the files in matlab they are not Cartesian even though my grid is Cartesian. I can reorder grid and data in matlab to form a structure grid, but I need to have my original Cartesian grid on which I have solved my case. My function object looks like this:

Code:

    cuttingPlane

    {

        type            surfaces;

        functionObjectLibs ("libsampling.so");

        outputControl   timeStep;

        outputInterval  15;



        surfaceFormat   raw;

        fields          ( U );



        interpolationScheme cell;



        surfaces

        (

            zNormal

            {

                type            cuttingPlane;

                planeType       pointAndNormal;

                pointAndNormalDict

                {

                    basePoint       (3.14 1 1.57);

                    normalVector    (0 0 1);

                }

                interpolate     false;

                triangulate     false;

            }



            xNormal

            {

                type            cuttingPlane;

                planeType       pointAndNormal;

                pointAndNormalDict

                {

                    basePoint       (3.14 1 1.57);

                    normalVector    (1 0 0);

                }

                interpolate     false;

                triangulate     false;

            }



        );

    }

Also when I have the interpolate on, my data show up on two different planes!! the second one usually is at a patch.
I would appreciate any input as I'm tight with time.
