You can manually define a Bloch boundary condition between two boundaries B1 and B2 by applying on boundary B1 a prescribed displacement of the form bndsim1(u)*exp(i*kx*L) where bndsim1() is a boundary similarity operator from Boundary B2. You should also specify that the displacement variables are complex and the Jacobian matrix is Hermetian.
