Importing physical property data as element-associated data

Importing physical properties as element-associated data:

• Reduces the time to import the model.

• Reduces the number of mesh collectors in the Simulation Navigator, which improves performance during pre-processing operations.

Importing physical properties as element-associated data

Use the Physical Properties list in the Data Compaction group of the Import Simulation dialog box to control whether the software imports existing physical properties as either physical property tables or as element-associated data for supported element types.

• Select All to import all physical properties as element-associated data. The software creates a separate mesh collector for each different type of physical property table. For example, if you import three different PSHELL entries, the software creates a single PSHELL mesh collector in the Simulation Navigator.Note: Even if you select the Use comment cards for entity names option, the software does not import any mesh collector names that are specified in comments in the input file ($).

• Select None if you do not want to import physical property table data as element-associated data. The software creates a separate mesh collector for each individual physical property table. For example, if you import three different PSHELL entries, the software creates three PSHELL mesh collectors in the Simulation Navigator.

• Select Selective to import specific physical property types as element-associated data. You can use options in the Element Associated Data Processing dialog box to control how the software imports property data into mesh collectors. For example, you can import a specific physical property type as a single mesh collector, or you can use the By Range option to have the software place the element-associated data into mesh collectors according to the values of their assigned IDs. With the By Range option, the software names the corresponding mesh collector using the name of the original physical property table and the range of ID values.You can also use the By Include Files option to control how the software imports physical property tables that are referenced in any included files.

Note:

If your model contains physical property data stored as element-associated data, you cannot use the Physical Properties View command in the Simulation Navigator to group meshes that share the same physical properties.

Managing element-associated data

After you import physical properties as element-associated data, you can use the spreadsheet-like interface in the Element Associated Data Manager dialog box to manage and modify the data as necessary. For more information, see Managing element-associated data.

Note:

For each element, any physical property data that is defined as element-associated data overrides any physical property data that may be specified in the associated mesh collector.
