Description
Objects in the model have defined relationships with each other that establish an explicit knowledge graph of the system being modeled. These relationships are either unidirectional (in and out) or bidirectional (inout) and can be traversed by the user while exploring the model. A summary of the existing relationships in Davinci are dicussed below:
Relationships must be given a Relationship Type when created. Select the Relationship Type, then the Relationship Object when creating a new Relationship
Base Relationships
| Property | Description |
|---|
Uses | Specifies the attribute referenced into equations of other attributes. Can be in and out. |
Reference | Used for between reference object and any other object type. Is out from the reference object and in to its target. |
SysML Standard Relationships
| Property | Description |
|---|
Performs | Specifies what object performs the intent of an action. Is out from the part and in to the action |
Subject | Specifies the object that realizes a requirement. Is out from the requirement and in to the target object |
Connect | Used for interface relationships between ports as defined by interface objects. Is inout. |
Part Specific Relationships
All of the following are defined as inout.
| Property | Description |
|---|
Data | Refers to the object that carries or provides the necessary information to perform an action. |
Power | Denotes the object that supplies energy or force to enable or achieve a desired effect or action. |
Mechanical | Relates to physical systems and processes that involve motion, force, or mechanical interaction. |
Optical | Describes actions or interactions related to light, vision, or the properties of optical systems. |
Chemical | Refers to the relationships and interactions involving chemical substances or processes. |
Electromagnetic | Defines the interactions or connections involving electromagnetic forces, such as electricity or magnetism. |
Thermal | Pertains to heat-related interactions or processes, such as temperature changes or thermal energy transfer. |
