Exporting wind tunnel data workflow

Once the model has been created and had loads applied in Tekla Structural Designer, the basic workflow for generating and exporting wind tunnel data is described below.

Display the Wind Tunnel Data ribbon

The workflow is initiated by clicking Wind Tunnel on the Analyze ribbon.

This enables the Wind Tunnel Data ribbon below:
You can work through this from left to right...

Add modal mass combinations

On the Wind Tunnel Data tab, click Add.

The Loading dialog box opens on the Combinations page with a new Modal Mass class of combination added in the left hand pane.
Rename the combination as required.
Select the loadcases that you want to add in the combination, and click >>
On the Applied mass tab, set the directions to be considered, and if necessary, specify the level below which mass can be ignored.
Click OK to save the mass combination.

Tekla Structural Designer adds the mass combination to the list of combinations in the Loading list.

Review the modal analysis settings

On the Wind Tunnel Data tab, click Settings

The Analysis Settings dialog opens on the 1st Order Modal page.
Select the total number of modes to be calculated.
Review and modify the other analysis settings according to your needs.

Run a modal analysis

On the Wind Tunnel Data tab, click Run Modal Analysis.

Tekla Structural Designer analyzes the model.

Review the results

After modal analysis the following results are available and can be reviewed as tabular data:

Masses, Center of Mass, and Mass Moment of Inertia by level,
Modal Frequencies,
Mode shape by level

Mode shapes can also be displayed graphically if required by switching to a Results View.

Export the report

To export all the tabular results that can be viewed in the Wind Tunnel Data View, click Export full report.

Alternatively, you can export just the tabular results that are displayed in the current view by clicking Export current view.
