[Gmsh] high-order fe visualization

[Giuseppe Zagari]

Hi,

I need to visualize the stress results of my fem calculation
for a 4 node high-order element and I am using

$ElementNodeData
....

for plotting the stress field and other.

But, in this way I can depict only a linear function
between two adjacent nodes instead  I would like to visualize the exact
solution in term of stress that is quadratic. How can I do that?


Best Regards,
  Giuseppe
