paraFoam wrong lines
 

Hi,

I would like to know if there is a way to get rid of those lines

Somewhere i found that they are due to the fact that paraview works with tetrahedra and creates this kind of artefacts when has to work with hexahedra.

Is there a way to have a more accurate visualisation?
