Hi, everyone

I want to know whether the global index of nodes in the mesh is the same with that of the variable.
Like this:
node[1] :: u[1]
node[2] :: u[2]
.
.
.
node[i]:: u[i]
.
.
.
node[n]::u[n]

After I solve my PDE, I use system::build_<discontinuous_>solution_vector to get the values of the variable. However, I found that I can't find they are identical. Could you give me some advice?

Thanks a lot.

Regards,
Yujie
