The Impact of Referenced Models on the Isight Model

When you create an internal or external referenced model, Isight uses the Reference component to control the referenced model. Creating internal and external referenced models in the simulation process flow can have an impact on the model.

For more information about the Reference component, see Reference Component in the Isight Component Guide.

Consider the following:

  • When you create a referenced component by copying an existing component and pasting by reference, Isight adds a Reference component for both the original and the referenced component.

  • Once an existing component is used to create a referenced copy (and is automatically given a Reference component designation), you cannot “unreference” the component. Deleting the associated Reference component leaves the referenced component with one less reference (unless you delete the last reference and choose to delete the referenced component along with it). However, you can create a non-reference copy of the reference component and delete the referenced version of the component.

  • The Reference component is used for all internal model referencing, including referenced copies of components and submodels. You can also use the Reference component to reference models published in the library and models in partner libraries when using a SIMULIA Execution Engine with federation capabilities. For more information, see Reference Component in the Isight Component Guide.

  • When you create a referenced component or a submodel, a new node labeled Submodels appears on the Design Gateway model explorer. This node not only provides a list of all submodels, but it allows you to perform such actions as copying or deleting a submodel.

  • When a component is used by reference, the Reference component automatically holds copies of all the component’s parameters being referenced so that they can be driven directly by the individual references. Changes made to the parameters in the component are automatically reflected in the reference components that refer to it.
