You can activate or deactivate the use of the analysis add-on in the Add -Ons tab of the ' Model General Data '. A green dot in front of the add-on description means that a license is available. An orange or blue point indicates that the use of the add-on is only available as a demo or part of a test version and the range of functions is limited.
When you have activated the add-on and defined the standard, the user interface is expanded to include new entries in the navigator, tables and dialogs. This means that the parameters of the time-dependent analysis are fully integrated into the user interface of the RFEM program.
