WaveSim - Mode Shapes Comparison for Finite Element Analysis and WaveCam

Finite element analysis (FEA) is a powerful method for the numerical prediction of the dynamic vibration behaviour of structures of all kinds. Based on the structure geometry, the material properties and the given boundary conditions, the modal parameters (natural frequency, mode shape and damping) of the structure can be calculated. This method is therefore an important tool in component and structure development (e. g. digital prototyping), which is reflected above all in shorter product development times. To validate and verify these models, measurements are required to adapt the models to reality.

WaveSim is a powerful comparison tool that validates your Finite Element Analysis (FEA) simulations by utilising real-time data from WaveCam, our advanced video-based vibration analysis software. This innovative approach improves the accuracy, robustness and reliability of your FEA simulations, ensuring that your designs reflect real-world conditions and optimising your products for real-world applications. Through advanced simulation comparisons, WaveSim helps you achieve greater accuracy and efficiency in your design and development processes.

    Mode Shape Comparison Between Simulation and WaveCam

    This software provides a link between simulation and WaveCam measurements and is used to verify and validate the numerical models.

    Import of mode shape results: Load UFF files with mode shape results from both WaveCam and external simulation software.

    Overlaying the simulation data: Overlay the imported simulation data on the 2D image from WaveCam for visual comparison.

    Frequency selection: Select specific frequencies from the simulation and WaveCam data to focus the comparison.

    MAC calculation: Perform the Modal Assurance Criterion (MAC) calculation to quantitatively compare the simulation data with the real data from WaveCam.

    Supports various simulation software via Universal File Format (UFF) mode shape import:

    • UFF 15: Contains 3D positions of geometry nodes and their colours or textures, coordinate systems.
