The specification tree contains the following items:
Analysis Manager
All the objects making up an analysis document.
Links Manager
All the links to other documents managed from the .CATAnalysis document, such as part or results data.
Finite Element Model
The model representation used for performing a computer-aided engineering analysis, consisting of the system representation and various environment action representations.
Nodes and Elements
The nodes and elements that can be created are OCTREE (GPS) type.
Properties
Any specification applied to define the physical properties (geometry) of the model:
Material and thickness (surface)
Connections
Imported composite properties
Nonlinear and Thermal Properties
Any nonlinear or thermal specifications applied to define the physical properties (geometry) of the model:
Amplitudes
Nondefault behavior of contacting surfaces
Shell property enhancements
Nonlinear Structural or Thermal Case
A procedure for the computation of the system response to applied loads under given restraints.
Element Assignment
The elements assigned to each mesh part.
Simulation History
The sequence of analysis steps that define the environmental actions on the system.
Initialization
A special Initialization step is created at the beginning of the Simulation History.
Connections
Enhancements to connections.
Fields
Initial temperature fields.
Heat Transfer Step
Field Output Requests
Generates field output that is saved to the output database file, typically for large regions or for the entire model.
History Output Requests
Generates history output that is saved to the output database file, typically more often than field output or for a smaller region of interest.
Loads
Generates thermal loading reflecting effects of convection and distributed and concentrated heat fluxes.
Boundary Conditions
Generates thermal degree of freedom restraints on a geometry selection.
Jobs
Analysis job definitions.
Display Groups
Analysis display group definitions.
Analysis Case Solution
Results data image requests.
Solution Sensors
Local or global sensors added to record or parameterize field or history output results, respectively, within a step.
