Editing Images

This task shows how to edit an existing image.

You can edit an activated or deactivated image.
If you want to edit a deactivated image, make sure that the parent entity is updated.

Open the sample26.CATAnalysis document from the samples directory.

Double-click the Von Mises Stress (nodal values).1 image in the specification tree to edit it.

The image is activated and the visualization appears.

The Image Edition dialog box also appears.

This dialog box proposes different tabs in accordance with the activated case type solution, and in accordance with the activated image you wish to edit.

You will find in the following table the available tabs and buttons in the Image Edition dialog box.

	Mono-occurrence solutions	Multi-occurrence solutions
`Deformed Mesh` image	Mesh Selections Preview	Mesh Selections Occurrences Preview
Other images	Visu Selections Preview	Visu Selections Occurrences Preview

Enter your parameters.
Click OK.

Some functionalities of the Image Edition dialog box are not available with the DMU Engineering Analysis Review product.

Mesh Tab

Deform according to: lets you visualize the deformation according to displacements.

In the case of Dynamic Response Analysis Case (Harmonic or Transient) with restraint excitation, you can specify if you want to visualize the image in an absolute axis (Absolute option) or in a relative axis (Relative option) using the button.

Absolute: lets you visualize both the displacement and the elastic deformation of the part.
Relative: lets you visualize only the elastic deformation of the part.

Display free nodes: lets you display free nodes (nodes that are referenced by any element).
Display nodes of elements: lets you visualize nodes of elements.
Display small elements: lets you choose to display or not the very small elements.
Shrink Coefficient: lets you shrink the element visualization.

Visu Tab

Deform according to: lets you visualize the deformation according to displacements.

Absolute: lets you visualize both the displacement and the elastic deformation of the part.
Relative: lets you visualize only the elastic deformation of the part.

All the other options in this tab (Types, Criteria, Options... button and options contained in the More>> frame) are not available in the DMU Engineering Analysis Review context.

Selections Tab

The Selections tab lets you limit the image visualization to a list of entities.

Available Groups: gives you the list of the available entities.

The available entities could be:

mesh parts (under the Nodes & Elements set in the specification tree)
pre-processing specifications (under the Restraints, Loads and Masses sets in the specification tree)
user groups (under the Groups set in the specification tree)

You can filter the list of the available entities using the Filter groups... contextual menu.
To know more, refer to Filtering Group Types.

button: lets you activate the visualization of all the available entities contained in the Available Groups frame.
button: lets you activate the visualization of entities selected in the Available Groups frame.
button: lets you deactivate the visualization of entities selected in the Activated Groups frame.
button: lets you lets you deactivate the visualization of all the selected entities contained in the Activated Groups frame.
Activated Groups: shows you the list of the entities you have activated the visualization.

Multi-selection is available.
In this case, the resultant selection is the union of the selected entities.
You can double-click an entity to activate or deactivate the entity visualization.
You can select entities directly in the specification tree or in the viewer.
Minimum value and the maximum value of the color palette depend on the selected entities.
If the Activated Groups field is empty, all the entities listed in the Available Groups field will be visualized.

In case of pre-processing specifications, the type of entities contained in a selection may be different from a specification to another.
For example:

a Clamp symbolizes a list of nodes
a Lineic Force symbolizes a list of edges
a Pressure symbolizes a list of faces

Filtering Group Types

Right-click in the Available Groups frame and select the Filter Groups Types... contextual menu as shown below:

The Filter Group Types dialog box appears.

User groups: lets you activate all the groups under the Groups set in the specification tree.
1D mesh parts: lets you activate all the 1D mesh parts under the Nodes and Elements set in the specification tree.
2D mesh parts: lets you activate all the 2D mesh parts under the Nodes and Elements set in the specification tree.
3D mesh parts: lets you activate all the 3D mesh parts under the Nodes and Elements set in the specification tree.
Connection mesh parts: lets you activate all the connection mesh parts under the Nodes and Elements set in the specification tree.
Specification groups: lets you activate all the entity under the Restraints, Loads and Masses sets in the specification tree.

Select or clear the desired check boxes.
Click OK.

For example, with the following analysis specification tree:

if you select only the User groups and the Specification groups check boxes, the Available Groups frame is updated as shown below:
if you select only the 3D mesh parts and the Specification groups check boxes, the Available Groups frame is updated as shown below:

Occurrences Tab

The Occurrences tab is available in the Image Edition dialog box only for multi-occurrence solutions.

This tab gives you the list of modes with the associated:

frequencies (Hz) for a Frequency Case and a Harmonic Dynamic Response Case
Buckling factor for a Buckling Case
Time (s) for a Transient Dynamic Response Case

You can then activate separately each mode of the multi-occurrence solution.

Preview Button

By default, the visualization process is launched after each modification in the Image Edition dialog box.

The Preview button allows you to launch the visualization process after performing all the needed changes in the Image Edition dialog box.

The Preview button is available only if you deactivate the Automatic preview mode option in the Options dialog box (Tools > Options...> Analysis and Simulation > Post-Processing).
To know more, refer to the Customizing - Post Processing section of the Generative Structural Analysis User's Guide.
