New question #102633 on DOLFIN: https://answers.launchpad.net/dolfin/+question/102633
Hi I've alluded to this problem before but the solution is not working (properly). What I'd like to do is the following (using the C++ interface): i. I create an object for each degree of freedom (no problem). ii. Each object generates a value (no problem). iii. I need to assemble these values into a vector that will be passed to a pde as the initial condition (major problem). Anders suggested the tabulate_coordinates function to obtain the coordinates of the dofs and Garth suggested the Dolfin::Set which doesn't sort the coordinates. This works for P1 elements but for P2 elements and above, it's not quite right. Could someone please provide a code snippet that shows how to: 1. Assemble individual values at each dof (with its coordinates) into a solution vector exactly as the pde would expect it. 2. Extract the individual values form the solution vector produced by a pde and associate it to a particular dof and its coordinates.
