Tree Structure of Structural Analysis Simulations
The specification tree of a structural analysis simulation is
composed of three main categories: Model,
Scenario, and Result. The following
picture represents a typical specification tree for a structural analysis simulation.

Tree Symbols
The data in the Model, Scenario, and Result categories are linked and interrelated. Modifying an entity that is linked to a scenario or a result of scenario can change the update status of the scenario or the result of scenario. The
,
, and
symbols that are displayed in the specification tree help you determine the relationships between the data.
To learn more about those symbols, refer to Structural Analysis User's Guide: Creating Structural Analysis Simulations: About Structural Analysis Simulations.
