Purpose

The Mass viewpoint enables to simply describe the non-functional aspect of mass in Capella.

Scope

Mass information can be added on a Physical Component or graphically in PAB diagrams.

Principles

On a Physical Component, a "Mass" annotation indicates the mass associated to a component. A "Maximal Mass" defines the upper mass accepted by a component.

When a component contains sub-components, recursively, the total mass is the sum of the mass of its sub-components and its mass.

Graphically, when:

  • Total mass < Maximal Mass: the Physical Component and associated annotation are displayed in green.
  • Total mass = Maximal Mass: the Physical Component and associated annotation are displayed in orange.
  • Total mass > Maximal Mass: the Physical Component and associated annotation are displayed in red.

Practice

The Basic Mass viewpoint enriches the Capella palette with a new section composed of one icon:

  • Mass: it enables to set the mass of a Physical Component Node or Behavioral Component.


Use of Mass:

  • Click on the icon and next on a Physical Component Node or Behavioral Component.
  • Set the current Value and Max Value in the 'Basic Mass' section of the Properties view.
  • The mass of the components containing the current component are automatically recomputed and the colors change if needed.


A Mass can be alone on the current diagram. That means that this Mass is applied on the Physical Component which contains the diagram (e.g., the Physical System).
