               <p class="para_item">RSSCON generates a multipoint constraint that models a clamped connection between a shell and a solid element. The shell degrees-of-freedom are put in the dependent set (m-set).  The translational degrees-of-freedom of the shell edge are connected to the translational degrees-of-freedom of the upper and lower solid edge.  The two rotational degrees-of-freedom of the shell are connected to the translational degrees-of-freedom of the lower and upper edges of the solid element face. Poisson&rsquo;s ratio effects are considered in the translational degrees-of-freedom. </p>
            </li>
            <li>
               <p class="para_item">The shell grid point must lie on the line connecting the two solid grid points. It can have an offset from this line, which can not be more than 5% of the distance between the two solid grid points. The shell grid points that are out of the tolerance will not be constrained, and a fatal message will be issued.  This tolerance is adjustable.  Please see PARAM,TOLRSC and PARAM,SEPIXOVR. </p>

                     <p class="para_item">In case of p-elements, the p-value of the shell element edge is adjusted to the higher of the p-value of the upper or lower solid p-element edge.  If one of the elements is an h-element, then the p-value of the adjacent edge is lowered to 1. </p>
