Hi All,


I have updated my openfoam version from of6 to of7 and encountered some issues with vtk surface files. In of6 I had triangulated files, which were very easy to handle in a python-vtk postprocessor. Now with of7 I get tri-, quad- and higher-polygons (see attachement: vtk_of6_of7.png). Is there a way to force openfoam to generate triangles?

I found a keyword "triangulate" (see code snippet) within the surface file and set this to "true" but had no effect.

Any idea how to get vtk's, which are always triangulated?





Code:
type            surfaces;
libs            ("libsampling.so");

writeControl    adjustableRunTime;
writeInterval   surfWriteIntervalVar;
     
/*
null
dx
vtk
raw
stl
*/

surfaceFormat   vtk;
interpolationScheme cellPoint;

x (1 0 0);
y (0 1 0);
z (0 0 1);
origin (0 0 0);

cuttingPlane
{
    type         cuttingPlane;
    planeType    pointAndNormal;
    pointAndNormalDict
    {
        basePoint    $origin;
        normalVector $x;
    }
    interpolate  true;
    triangulate  true;
}
