Bilinear functions over QUADs rendered incorrectly
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Hi,
I created a 5x5 uniform grid of quadrilaterals on the unit square and wrote a VTK (.vtu) file with data symmetric w.r.t. the midpoint of the square. In each of the quadrilaterals, I expected the function to be rendered as a bilinear function. This seems to happen, except for the elements in the corners of the domain. This way, the solutions appears asymmetric.
The VTK file is attached.
Cheers, Nico
