Dear Zhenghuai Guo, 
  1. Is the values in the vector U storing the displacement value “u”, the same order as the dofs? Say the first value in the vector U corresponds to dof 0 and the 100th value in the U corresponds to dof 99. - YES
  2. When I do ...

             It appears that it show duplicated coordinates as you can see every two coordinates are the same. Is this because that the mesh is two dimension and each node has two dofs – one for x and the other for y? - YES


  1. What is the different between dof and basic_dof? I can see there are basic_dof_on_region() and dof_on_region() for the mesh_fem mfu. - You can reduce the mesh_fem, either to a specific region or with some linear transformation. So, the basic_dof refers to the unreduced mesh_fem.
