Main features

Geometry Building
Interactive interface to create, modify, assemble standard elements or complex structure with global and local coordinate systems. Import from external software in universal file format.

Direct acquisition & Signal processing
Dedicated interface for modal acquisition with impact hammer, shakers or under operational conditions to obtain:
    * FRF H1, FRF H2 for EMA
    * Power Spectral Density, Half Power Spectral Density for OMA 

Operating Deflection Shape (ODS)
ODS is a great tool to visualize dynamically the vibration deflection shape of mechanical components during their normal operation.
It offers rapid visual feedback on the deformation of a structure in both time and frequency domain.

Experimental Modal Analysis (EMA)
Using an impact hammer or shaker(s), several identification methods allow one to determine modal parameters: frequency, damping and mode shape. Users can perform Single Input/Multiple Output (SIMO) method for a first approach and Multiple Input/Multiple Output (MIMO) techniques to make a more thorough analysis.

Operational Modal Analysis (OMA)
OMA is a very interesting technique for large structures or test items that are not easily excitable (e.g., civil infrastructures). With this method, modal parameters can be estimated without a known, controllable excitation signal.
