We will create a new design scenario for the random vibration analysis. This will preserve the natural frequency (modal) analysis setup and results, as well as those of any other analysis type that has been run previously.
If you are continuing from a prior Truss Tower analysis and are still in the Results environment, click the FEA Editor tab at the top of the browser (tree view).
Click Analysis Change Type Linear Random Vibration.
NoteYou can also change the analysis type by right-clicking on the Analysis Type heading in the browser. Choose Set Current Analysis Type from the context menu and select one of the available analysis types.
Click Yes to create a new design scenario rather than changing the analysis type of the existing one.
