Difference in .pch and .h3d file Plot
My Problem is, that a Plot from the .pch-file data is different than the Plot in HyperGraph from the same solve. The Data come from a Frequency Response Analysis with an acceleration output in a frequency range from 0-500Hz. The Problem is that the max. values of the Punch file are different to the values of the .h3d file, as shown below. Any idea why?
The HyperGraph Plot has a peak at 105 Hz with an acceleration of about 3.8g
The Plot from the .pch file (Plot with MATLAB) has a drop at the Point where the peak should be (only 0.459g at 105 Hz). As you can see, this problem has every curve.
