Periodic boundary conditions in a 1D situation

Hi,

I am trying to apply a model of 7 dependent variables on boundary of a circle, thus using a simple 1D line. I would like continuous and smooth boundary conditions. Using the Periodic boundary conditions I can take care of the continuous part, but I can't seem to adapt the Neumann BC to be the same (function in time) at each end point rather than a fixed value.

COMSOL seems to be satisfied when I use u in periodic BCs and I am hoping it is treated as the vector of all seven dependent variables...

Can I adapt the Neumann BCs so my waves can continue?
