[Paraview] [newbie] show grid in paraview - wireframe shows triangles instead of quads...

[newsboost]

Hi all,

[newbie question]: I want to show my mesh/grid in paraview and turn on 
"wireframe" mode. But this shows triangles instead of quads... I 
colleague of mine says that on his windows pc the correct quad mesh is 
shown but on my linux pc, I only see triangles...

Please help me understand how to see the true grid instead of the 
triangles...

Thanks.
