Contour Plot in a Modal Analysis (HyperView)

Lukas Kneer_21880

Hello, i have a question about the function "Contour" in HyperView. I don't understand the values of the Contour Plot in case of a Modal Analysis. My Model has 65 modes in the range from 0-500Hz, but the Contour Plot shows values, which probably have nothing to with the values of the modes. Can anyone help me, what these values stand for?

Hi, This is related to the concepts of vibration analysis. Modal analysis solves for eigenvalues (frequencies) and their wings vectors (mode shape). The contour shows you just the eigenvector/mode shape. It's absolute magnitude doesn't have a physical meaning. It can be normalized by the solver too. For frequencies, you should look at the top left of your screen. 4.52
