Hello again!
I’m still a beginner at Fenics and i’ve been learning to simulate a shallow-water problem using OpenTidalFarm which uses Fenics library. I’ve tried using global tidal model as the boundary tidal forcing, yet Newton Solver couldn’t reach convergence, which i think is due to the little amount of data for interpolation on my domain.
Hence i had an idea to use tidal prediction from my local tidal research organization. Problem is, that the tidal predictions are only defined per specific coordinates like this :

Is it possible to define a node-specific periodic boundary conditions in Fenics? If not, how could i implement such periodic datas in my boundary?
Thanks in advance!
