The Fluid-Pipe Interaction, Fixed Geometry (
) interface can be used to model problems where the forces from the fluid in a piping system act as structural loads. The structural deformations do not affect the flow.
You add a predefined Fluid-Pipe Interaction, Fixed Geometry interface from the
Fluid-Structure Interaction (
) group in either the
Structural Mechanics branch (
) or the
Fluid Flow branch (
) of the
Model Wizard or
Add Physics windows.
Pipe Flow and
Pipe Mechanics interfaces are then added to the Model Builder.
In addition, the Multiphysics node is added, which automatically includes the multiphysics coupling node
Fluid-Pipe Interaction.
