[Gmsh] Post processing 2nd Order Elements

[Shi Jin]

Hi there,

I am trying to visualize data from a FEM simulation using second order Taylor-Hood elements. Although I was able to get some image it is not the second order elements I am trying to see.  Please take a look at the attached image.

 
I am using the .msh file format. The mesh was loaded without problem in second order. However, I am not exactly sure what tags I should use for the $NodeData section. I am using the same one for first order elements:
$NodeData
1
"velocity-2"
1
0
3
0
1
39
12   -0.00000
...
I am not sure what the usage of the first a few tags before the one specifying the number of nodes (39 above).
If you could give some advice, I would greatly appreciate it.
