The Beam Connection node is obsolete, and has been superseded by the Shell-Beam Connection multiphysics coupling. It cannot be added in version 5.3 and later, but may be present in models created by earlier versions of the software.
You are advised to update your model to use the new multiphysics coupling instead, since the Beam Connection node will be removed in future versions.

Using Selected edges makes all selected edges rigidly connected to the point on the beam.

|
For Distance (automatic), all parts on the shell edge, which are within the default distance from the beam point, are connected. This distance is determined by the cross section properties of the beam. It is contained in the variable beam.re in The Beam Interface.

|
For Distance (Manual) enter a Connection radius rc. All parts on the shell edge, which are within the given distance from the beam point, are connected.
|
•
|
For Connection criterion enter a Boolean expression in the text field. The beam is connected to the selected shell edge wherever the expression has a nonzero value. The default value is 1, which is equivalent to using the Selected edges option.

For Shared select an Offset definition — Along shell normal (the default) or Offset vector. For Along shell normal enter an Offset ζ. For Offset vector enter values for d0 in the table. The offset is the vector from the reference surface of the shell to the actual position of the beam. The Offset vector is interpreted in the coordinate system selected in the Coordinate System Selection section.

|
For Parallel enter a value for the Parallelism tolerance Δθ. The default is 1 degree. The two edges are connected only where they are parallel within the specified tolerance.

Using Selected boundaries makes all selected boundaries rigidly connected to the point on the beam.
