3.3 Creating topologies

To couple and decouple components, you have to recreate the assembly topology in the design area, by adding components, linking the interfaces, and adding stiffness information and loads. The idea behind the design area is to allow you to visualize the assembly in the simplest possible way. For this reason, we have decided to leave out all the complexity of the 3D to let you work with a simpler but effecting 2D environment. A 3D viewer will be implemented in a later stage, to allow you to better visualize components orientation, etc.

Creating topologies

To create the desired assembly, you need to recreate its topology in the design area. To do so, you need to add all the components and link their interfaces, adding stiffness and loads when required or desired. All components and models you want to add to the design area need to be in the active library.

Adding components and loads

You need to add all component substructures of your assembly in the design area. Components can be generated either from tests or simulations. If desired, you cal also add lodas, such as Blocked Forces.

To add components and loads to the design area, complete the next steps:

  1. Open the fly-in library.
  2. Drag and drop the component or load to the design area.

Coupling interfaces with rigid links

To rigidly connect components, you need to add links to between their respective interfaces.

To create a rigid link between two interfaces, complete the next steps:

  1. Click the link tool .
  2. Click and hold on the first interface.
  3. Release on the second interface.

Coupling interfaces with compliant links

If you want to have a compliant coupling between two interfaces, you have to add a stiffness model to an existing link.

To create a compliant link between two interfaces, complete the next steps:

  1. Create a link between two interfaces.
  2. Drag and drop a stiffness model on the link.

The added stiffness is visualized as a circle on the link in the design area.

Decoupling components

In COUPLE, you can also decouple components from assemblies. This is needed, for example, when you need to decouple transmission simulators from a component.

To decouple a component from an assembly, complete the next steps:

  1. Create the topology in the design area.
  2. Select the component to decouple in the design area.
  3. Open the Inspector.
  4. Check the Decouple checkbox.

Creating a topologies with blueprints

Instead of directly creating the final assembly with all the components, you can also create an empty topology of the assembly and fill it in with components, loads and stiffness at a later stage. You can also create interfaces and link blueprints in advance.

Adding blueprints

You can add empty blueprints to the design area that you can fill with components or loads at a later stage.

To add a blueprint to the design area, complete the next steps:

  1. Click .
  2. Click into the design area.

Adding interfaces to blueprints

You can add interfaces to the empty blueprints in order to link them with other blueprints.

To add interfaces, complete the next steps:

  1. Click on the outer border of the blueprint.

Adding data to blueprints

Blueprints are empty topology items. You need to fill them with data to use them in the computation.

To fill out blueprints, complete the next steps:

  1. Open the fly-in library.
  2. Drag and drop the model from the fly-in library on the blueprint.

Mapping models and topology interfaces

When filling out blueprints, you need to map their interfaces with the model interfaces.

To map the interfaces, complete the next steps:

  1. Drag and drop the model interface to the topology interface.

You can edit the interface mapping of existing components in the Inspector.
