hi,
I applied "element=p:2" and "OutPutfile = toto.res "in my sif file.
I have 2 short questions about the nodes :
1) From my output file, I'd like to identify the kind of node, i.e. is it a node from my original mesh or an added node (from the quadratic requirment)?
2) If my original mesh has 100 nodes, can I considere that the numbers greater than 100 are assigned to the nodes of the quadratic mesh?
Thank you for your reply.
identify the kind of nodes (quadratic or not)

Hi
The p-element basis is not nodal. Only the lowest order solution is associated to nodes. You can use higher order nodal elements but they should be provided in the initial mesh.

Thank you Peter for your reply.
In my output file, I can see :
...
Number Of Nodes: 1521
Time: 1 1 1.00000000E-002
displacement 1
Perm: 5267 5267
...
So I'd like to export only the 1521 displacement's results corresponding to the original nodes. Is it easily possible ?

If you use Paraview to post-process it will save the data to a file. If you want to write directly from Elmer, look at the SaveScaler solver in the models manual.

Hi
If you want to parse yourself then ElmerPost format might be useful too. Or Gmsh output format.
For p-elements the first dofs in line relate to the permutated list of linear nodal dofs.
