give specific values for every mesh point of a boundary as boundary condition

hey everybody,

is it possibly to give different values for all points of the mesh on the boundary, respectively?

for example, just a vector containing as many values as i have boundary mesh points, or something including the coordinates/mesh point coefficients -- specifically, i want to use a solution of another study at one boundary as new boundary condition for another study, both at the same geometry+mesh. should be possible, no? (in fact, i want to use the old solution, but add to every value a time-dependent term, but this should work then as well.)

please let me know if you know anything helpful, thanks alot.

kind regards and all best,
sabine
