Hi Daniel, Thanks for your prompt reply. While in case of mesh movement, the vertices are independent. However, if want to add something to the solution vector at dofs of a vertex shared between processors, This mesh movement code wont be able to do that, It will add that value twice for the dofs at the shared vertex.
What could be an ideal way to do that? Will checking that the dof is a locally owned dof by using the is_element of the indexset of locally owned dofs help ? Will this be slow ?
