Hello ,



I am using OF2006 release and I want to sample surface data for post-porcessing. Here is my file:

/*--------------------------------*- C++ -*----------------------------------*\
| =========                 |                                                 |
| \\      /  F ield         | OpenFOAM: The Open Source CFD Toolbox           |
|  \\    /   O peration     | Version:  v2006                                 |

|    \\/     M anipulation  |                                                 |
\*---------------------------------------------------------------------------*/
 
surfaces
{
    type        surfaces;
    libs        (sampling);
    writeControl    timeStep;
    writeInterval    10;

    surfaceFormat    vtk;
    fields       (p U T k epsilon);

    surfaces
    {

        zNormal
        {
            type    cuttingPlane;
            planeType    pointAndNormal;
            pointAndNormalDict
            
            {
                point    (0 0.126 0); // Overrides default basePoint (0 0 0)
                normal       (0 0 1);      // $z: macro for (0 0 1)
                
                interpolate        true;
            }
            
        }


    }
}

Somehow while running the case, the surface files are saved as .vtp and not as .vtk. When I open paraview, I can't read these files. (Also the time doesn't seem to be included). Does anyone know how to overcome this?

This is a feature, not a bug. What you are looking for are the additional format options. Eg,

formatOptions
{
    vtk
    {
        legacy true;
        // format ascii;
    } 
}

If they still cannot be read, it could actually be a bug. Would be useful to know if it is broken in v2012.

You can also type in the terminal (or save it on an AllRun file)


foamToVTK -legacy


this will save it as vtk instead of vtp
