I think I did not make it clear to you. It is great to get the displacement values at arbitrary geometrical locations by interpolation. As you mentioned, this can be heavy. So I think at the moment I only need the values at the nodes. So I am now trying to obtain the node coordinates and the corresponding displacement values by dofs.
I need this information to calculate the spatial displacement distribution functions. Thank you

Dear Zhenghuai Guo,
Probably you can try to do this with the methods from http://getfem.org/userdoc/interMM.html.
In particular, have a look at
Interpolation on a cloud of points:
I assume you can create a cloud of points from a single point.
But the above is a "heavy" tool which involves interpolation. Of course if you know that you have a node in that specific location, you can extract the degrees of freedom from the displacement vector.
So, let me know what you're using it for.
