Figure 257: Active unit configuration list
In the example above, in addition to the three default files listed, two other configurations are present:
Legacy Configuration
My local configuration
When you select one of these files in the list and click OK, that configuration is applied to the active system.
Note
If you configured personal unit settings in a previous version of Simcenter Amesim through the Preferred Units Preferred Units dialog box, these configurations will be present in the Active unit configuration list, as long as the Starting directory is the same in the current version as in the previous version. Such units are listed as Legacy Configurations:
If your Starting directory is different in the current version, previous configurations can be added to the list manually. See Import Unit Configuration.
