Function to create the A3 eigenvalue analysis.
Input:
- project (obj): VIIA project object containing collections of fem objects and project variables.
- modes (int): Number of eigenmodes to take into account in the analysis. This value is only used in eigenvalue
analysis (analysis type 'EIGEN'). Default value 1000.
Output:
- Creates and returns the A3 with all settings for VIIA.
