Calculation Diagrams

During the calculation, a diagram showing the course of the maximum displacement is displayed (see the image Calculation Progress ). You can also check this diagram in more detail after the calculation. Moreover, you can create user-defined calculation diagrams (CD) that display the convergence behavior on specific nodes of members, surfaces or supports. You can find the Calculation Diagrams in the Navigator – Data.

Navigator Category "Calculation Diagrams"

In the "New Calculation Diagram" dialog box, you can define the criteria for displaying the results in the diagram.

Dialog Box "New Calculation Diagram"

Main

If no results are available yet, only the Main tab is available.

Diagram Type

There are several diagram types available in the list:

• 2D | Basic: You can individually specify which results are to be displayed on the horizontal and vertical axes of the diagram.
• 2D | Convergence Diagram: The diagram shows how the maximum deformation develops during the calculation.
• 2D | Group: The diagram can display the results of multiple diagrams that are available for the same objects for the same result types.
• 2D | Chained Analysis Diagram: You can display the results of an initial load case and a final load case to analyze the effects of multiple loading and unloading, for example (hysteresis diagram).

Other input options in this dialog box are adapted to the diagram type that is set.

Source

In the list, you can select the "Analysis type" to whose results the diagram will refer. If no "Analysis Add-on" has been activated in the model's Base Data, only the "Static Analysis" is available.

Define the load case or load combination whose results are to be displayed in the diagram. Result combinations and design situations are not available for selection, because the diagram cannot display any enveloping results.

Horizontal Axis / Vertical Axis

In these two dialog sections, you can define the result criteria that are to be applied to the x- and y-coordinates. The options in the "Result type" list depend on the Diagram Type.

Result Types for "2D | Basic" (Left) and "2D | Convergence Diagram" (Right)

Set the "Result type" for the horizontal axis. Usually, it is the "Increment". Then, you can assign a deformation or internal force or moment to the vertical axis for a basic diagram, or the maximum deformation for a convergence diagram.

If a basic diagram is set, select the displacement, rotation, or internal force and moment type in the "Value" list. Then, define the "Object" whose result you want to see in the diagram and specify the "Node" for which this is done.

Defining Criteria for Vertical Axis

In the case of a Chained Analysis Diagram, you can define load cases or combinations to display the overall result of construction or load conditions, for example, to analyze the hysteresis behavior of a plastic material model.

Diagram

The diagram is displayed as soon as the results of the load case or load combination are available. When you change a criterion, the graphic is updated automatically. In the Diagram tab, you can check the diagram in full view.

The green bar below a convergence diagram (see the New Calculation Diagram dialog box) corresponds to the convergence curve as it appears in the Calculation Progress window.

The buttons below the diagram have the following functions:

List Button with Options	List button with options for the orientation of an abscissa X and an ordinate Y
List Button with Options	List button with options for the linear or logarithmic display of the X and Y values
	List button with options to print a diagram
	Increase the length of an abscissa X
	Decrease the length of an abscissa X
	Increase the length of an ordinate Y
	Decrease the length of an ordinate Y
	Display a diagram with filled gradient
	Specify the maximum and minimum value

Table

The Table tab is available as soon as the results of the load case or load combination are available.

Table with Result Values of Calculation Diagram

The table lists the values that have been calculated in the individual iterations and load increments. As mentioned above, the results of the individual load increments must be saved when performing an incremental calculation.

The values of the selected row are indicated on the right in the diagram.

Diagram

The Diagram tab is available as soon as the results of the load case or load combination are available.

Convergence Diagram for Incremental Calculation

In this tab, the diagram is shown in full view. This facilitates targeted evaluations.

The list button provides various options that you can use for the documentation of the diagram (see the chapter Graphics).
