Browsers supply a great deal of view-related functionality in HyperMesh by listing the parts of a model in a tabular and/or tree-based format, and providing controls inside the table
that allow you to alter the display of model parts.
Connectors are geometric entities (not FE) used to create connections between components. Connectors are used to realize
FE idealizations of the physical connection. Just as you create an FE mesh on a surface, you create FE connections
by realizing a connector.
The HiLock realization type can be used for any more or less parallel combination of PSHELL and PCOMP elements, and creates a 1D element construct consisting of RBAR, CBAR and CBUSH elements.
Use the RBE3 Load Transfer realization to create MPC’s using RBE3 elements between the nodes of shell-shell, shell-solid
or solid-solid groups by using spot connectors.
The Radioss acm (shell gap contact and coating) realization creates hexa clusters between shell components. Contacts get defined
between the shell components and the appropriate hexa nodes. A heat affected zone for the shells from ultra high strength
steel material is also created.
There are many advantages to the way connectors store information. Not only does this local storage allow you to edit
the connector definition, it also allows you to review connector details and the quality of the realization.
Most of the information stored in the connector entity can be exported to a master connectors file, which contains
connector entity information such as location, link entity, link entity state, link entity rules. The exported file
may also contain metadata information stored in the connector.
Create weld points at a predefined pitch distance so that the model build process can continue without the need to
wait for the published weld data from CAD. Autopitch is useful when working with elements, not geometry.
Perform automatic checks on CAD models, and identify potential issues with geometry that may slow down the meshing
process using the Verification and Comparison tools.

Restriction: Available for OptiStruct, Nastran and Abaqus solver
interfaces.
Solid-Solid
Shell-Shell (Face to Face)
Shell-Shell (Edge to Face)
For successful realization of these connectors, the non-normal projection option needs to
be active. Otherwise the projection onto an edge does not work.
Shell-Shell (Edge to Edge)
For successful realization of these connectors, the non-normal projection option needs to
be active. Otherwise the projection onto an edge does not work.
Shell-Beam
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.
Note: This option
is only available for nodes as connector location, and only if the center definition is
set to use connector position for center.
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.
use connector position for center
The exact position of the connector becomes the center of the RBE3 element.
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.
