Set value of property for element instance
This function is part of the instance API that you can use to analyze the model
iteratively, element by element.
instance refers to the element
instance on which the iteration is being performed.
Set Mass Property Value
Load the Small UAV model, create an architecture instance, and set the mass property value of a nested component. Get the new value to confirm the change.
scExampleSmallUAV model = systemcomposer.loadModel('scExampleSmallUAVModel'); instance = instantiate(model.Architecture,'UAVComponent','NewInstance'); setValue(instance.Components(1).Components(1),... 'UAVComponent.OnboardElement.Mass',2); [massValue,unit] = getValue(instance.Components(1).Components(1),... 'UAVComponent.OnboardElement.Mass')
massValue = 2 unit = 'kg'
instance — Element instance
architecture instance | component instance | port instance | connector instance
property — Property
character vector | string
Property, specified as a character vector or string in the form
value — Property value
double (default) |
enumeration class name
Property value, specified as a data type that depends on how the property is defined in the profile.
|analysis||Analysis is a method for quantitatively evaluating an architecture for certain characteristics. Static analysis analyzes the structure of the system. Static analysis uses an analysis function and parametric values of properties captured in the system model.||Use analyses to calculate overall reliability, mass roll-up, performance, or thermal characteristics of a system, or to perform a SWaP analysis.|
|analysis function||An analysis function is a MATLAB® function that computes values necessary to evaluate the architecture using properties of each element in the model instance.||Use an analysis function to calculate the result of an analysis.||Write Analysis Function|
|instance model||An instance model is a collection of instances.||You can update an instance model with changes to a model, but the instance
model will not update with changes in active variants or model references. You
can use an instance model, saved in an ||Run Analysis Function|
|instance||An instance is an occurrence of an architecture model element at a given point in time.||An instance freezes the active variant or model reference of the component in the instance model.||Create a Model Instance for Analysis|
|stereotype||A stereotype is a custom extension of the modeling language. Stereotypes provide a mechanism to extend the architecture language elements by adding domain-specific metadata.||Apply stereotypes to elements: root-level architecture, component architecture, connectors, ports, data interfaces, and value types of a model. A model element can have multiple stereotypes. Stereotypes provide model elements with a common set of property fields, such as mass, cost, and power.||Extend Architectural Design Using Stereotypes|
|property||A property is a field in a stereotype. For each element the stereotype is applied to, specific property values are specified.||Use properties to store quantitative characteristics, such as weight or speed, that are associated with a model element. Properties can also be descriptive or represent a status. You can view and edit the properties of each element in the architecture model using the Property Inspector.|
|profile||A profile is a package of stereotypes to create a self-consistent domain of element types.||Author profiles and apply profiles to a model using the Profile Editor. You can store stereotypes for a project in one profile or in several. Profiles are stored in XML files when they are saved.|
