[vtkusers] Finite element data

[Burlen]

Hi Joao, VTK does have the quadratic hexahedra cell type so you will be able 
to visualize data at the nodes of your cells easily. As far as your other 
data, there are a few options that I can think of. If have the situation 
where you can find one value(maybe anaverage) per cell, you can associate 
that value with its respective quadratic hexahedra cell. Alternatively you 
could interpolate your vector and or scalar data to quadratic hexahedral 
nodal locations. Alternatively you could add points and associate either 
vector data or scalar data with those points. To do this you'd need to 
transform your local coordinates into global coordinates. I hope this gives 
you some ideas, or sparks some further discussion.
