Node number

I'm solving a weak form problem on a membrane geometry. I meshed the geometry using "Free Triangular". Then solve the solution. Based on the solution, I calculated two derived values: (1) sqrt(u^2+v^2+w^2) which is the displacement and does not involve any derivatives (2) some quantity involves using "dtang()", which is tangential derivatives on the boundary.
I tried to export these two scalar fields to txt files, but I found that the node numbers in the two txt tiles are totally different.

scalar field (2)

I'm using the same mesh, why the node number is different? Is is because (2) use "dtang()"?
Thanks a lot.
