    If my understanding of the 2d manual is right, 1d and 2d area boundaries must be connected by lateral structure right?

    Well when the flow runs in parallel with the 1D/2D connection then you can use a lateral structure. When the flow run perpendicular then you can connect the 1D cross section to the 2D flow area directly. Both options are outlined in the 2D Modeling User Manual.
