For successful realization of these connectors, the non-normal projection option needs to be active. Otherwise the projection onto an edge does not work.

This situation is a very specific and requires some preparation to be successful, since the projection onto 1D elements is not supported. In this situation, you need to enable the non-normal projection checkbox for the projection onto the edge. In addition, the node of the 1D element needs to be defined directly as a link. Normally this is done during connector creation by activating add node location as link.

Center definition options include:

use shortest projection for center

The closest node becomes the center of the RBE3 element.

During the realization, based on the connector position and the tolerance, the closest links are determined up to the number of required layers (num layer). All other link candidates are not taken into account for the next step. The closest node is also determined and becomes the center of the RBE3 element. Based on this center position, all nodes within the given tolerance (distance center to node) and belonging to the remained links are attached to the RBE3 element.

Note: If the connector has been created with the option add location node as link, the use shortest projection for center option is ignored and the linked node becomes the center of the RBE3 element.

The exact position of the connector becomes the center of the RBE3 element.

Figure 7. Use Connector Position For Center

use coarse mesh for center

During the realization, based on the connector position and tolerance, the closest links are determined up to the number of required layers (num layer). All other link candidates are not taken into account for the next step.

From the remaining links, the one with the coarsest mesh is identified and a node on this mesh (close to the perpendicular connector projection) becomes the center of the RBE3 element. Based on this center position, all nodes within the given tolerance (distance center to node) and belonging to the remaining links are attached to the RBE3 element.

Note: If the connector has been created with the add location node as link option, the use shortest projection for center option is ignored and the linked node becomes the center of the RBE3 element.
