Hole

Use the subnode to define internal holes for a beam cross section. One feature must be added for each internal hole in the parent Homogeneous Cross Section.

Beam Properties

If you use the Beam Cross Section interface coupled to a Pipe Mechanics interface, the two interfaces have to agree on the type of cross section. Since circular pipes are very common in piping systems, they are to some extent treated as a special case in the Pipe Mechanics interface.

Select the — or . This setting is ignored for all cases, except in a coupled analysis with the Pipe Mechanics interface.


	The settings for layers only present in 3D, since in 3D the physics interface formally uses the layered technology. There is no need to make changes here.

Fluid Loads

The fluid loads are used for computing the stress from internal pressure. These inputs have a purpose analogous to the entries in the Section Forces and Twist sections in the node.

Enter the , pi, and the , po.

After changing data in this section, you do not need to compute the study for this physics interface again once is has been solved. It is sufficient to do an to get the stress plots updated.

•

If this interface is referenced in a Beam–Beam Cross Section Coupling, the inputs in this section are not accessible, since the cross section forces are transferred from a Pipe Mechanics interface.

Boundary Selection

You should select all boundaries around a certain hole from the list (). The option is not relevant.
