Experimental modal analysis in DIRAC – Workflow

In this article, you will learn all the steps needed to perform Experimental Modal Analysis (EMA) in DIRAC.nse or dir-ema and dir-prepare. You do not need all DIRAC modules, so you can also use DIRAC just for performing modal analysis.

To perform EMA in DIRAC, we recommend following these steps:

• Step 1: Choose the dataset.
• Step 2: Run first computation with smart settings.
• Step 3: Fine-tune the settings and manual pole picking.
• Step 4: Visualize results.
• Step 5: Export results.
