The continuum coupling method constraint distributes the forces and moments at the reference node as a coupling nodes force distribution only.No moments are distributed at the coupling nodes. The structural coupling method is particularly suited for bending-like applications of shells when the coupling constraint spans small patches of nodes and the reference node is choosen to be on or very close to the constrained surface.The constraint distributes forces and moments at the reference node as a coupling node-force and moment distributing. 一般distributng选择C就行了，S的更适用于薄壳弯曲。
