[vtkusers] vtkContourfilter produces uncomplete surface when cutting hex mesh

Hi All,

this is my first email here.

I use the vtkContourFilter on an unstructured 3D Grid.
Case 1: Cells are Tetraeder (Type 10) --> everything is fine.
Case 2. Cells are Hexaeder (Type 12) --> the resulting surface is not 
complete. Each cutted face is divided into 4 triangles. An rectangle 
would fill the whole.

My question: Is there any method to produce a complete surface from a 
Hexaeder mesh using the contour filter without any wholes?

Looking forward to your help
 
Best regards

Hans
