Identifying results

Use the Identify Results command to probe, display, and save results for specified nodes and elements.

When you have identified nodal or elemental results of interest, you can:

• Save a particular selection to a group for display purposes or for further pre-processing.

• Write node and element data to a spreadsheet or comma-separated text file.

• Export node and element data to a table field.

• View and customize the identified data in the Information window, and print or save it.

Note:

• For Simcenter 3D Multiphysics cyclic symmetric results, you can identify results in any displayed sector, and the identified results include the sector ID.

• For Simcenter 3D Multiphysics Fourier axisymmetric results, you can identify results for any sector of the displayed 3D model, and the identified results include the theta value.

Specifying the nodes or elements to probe

To specify the nodes or elements to probe for results, you can:

• Select entities in the post view in the graphics window.

• Select entities by node or element ID.

• Specify minimum results values, maximum results values, or a range of results values.

• Select entities by group or selection recipe.

The Identify dialog box displays a summary of the minimum, maximum, sum, average, and weighted average results values at selected entities. For single-node selection recipes, the selection recipe name also appears.

For more information about weighted averages, see Displaying weighted average.

Marking selected nodes or elements on the model

You can display either entity IDs or results values on the probed entities in the post view. For example, as shown in the figures, you can interactively probe the model and display the results value at each node you select. Or, you can select nodes by results value criteria, and display the corresponding node IDs.

Tip:

Use the Menu→Preferences→Post Processing→Identify command to set the numeric format of the results.

Setting up the results display

Use the post-processing Cutting Plane Options command to create cutaways and cross section displays to assist you in identifying entities. Drafting commands, such as Clip Section, do not affect the visibility status of post-processing results. For example, the Identify Results command selects entities that the Clip Section command has hidden. Use the Cutting Plane Options command instead to set the visibility of result entities.

For information about setting up cutaways and cross section displays for post-processing results, see Cutting plane displays.

Displaying weighted average

In the Identify dialog box, you can select the Weighted Average check box to display the weighted average.

Displaying the weighted average is only available when you set the Pick option in the Identify dialog box to Mesh, Feature Face, Feature Edge, Polygon Face, and Polygon Edge. It works for 1D, 2D and 3D elements as appropriate for the selected Pick option.

The following table shows the different types of weighted averages displayed based on the Pick option and the type of element selected.

Pick option	Selected elements
3D	2D	1D
Mesh	Volume	Area	Length
Feature Face	Area	Area	N/A
Feature Edge	Length	Length	Length
Polygon Face	Area	Area	N/A
Polygon Edge	Length	Length	Length

The following figures show examples of weighted averages returned for selected elements.

Saving identified results to a group

You can save the identified nodes and elements to a group. You can use this group like any other to control results visibility in post-processing, or to identify areas of your mesh or model requiring further refinement in pre-processing.

Note:

If you are post-processing results associated with a solution, the group is saved to the Simulation file as part of your model. If you are post-processing imported results, however, the group is stored temporarily only as long as the imported results are loaded, and is not available in the Group Manager dialog box.

Saving identified results to a field

You can save identified results to a table field. You can plot, edit, define spatial distribution boundary conditions, and export table fields from identified results like any other field.

Saving identified results to a CSV file or spreadsheet

You can write the identified data (node or element IDs, values, min, max, sum, and average) to a spreadsheet or a CSV (comma-separated values) file. You can use this data for further analysis, graphing, or report preparation.

Viewing and customizing identified results in HTML format

You can view the identified data in the Information window, where you can hide or display sections of the data, as well as edit it. For example, you can remove or edit a value. You can then save the edited data to an HTML file. You can also print the data.
