Altair Hyperworks 2022.1 Random Frequency Response Analysis of a flat plate (OST-1325)

Hey,
In this video I will take a closer look on random frequency response. These are helpful links to dive deeper into this topic:
- blog.endaq.com...
- Awesome PSD animation: • What is a power spectrum?
- Good explanation about the frequency normalization nature of PSD compared to FFT: • Power Spectral Density
- Deeper Dive inta Nastran: • Frequency Response and...

Hello doctor, Found your video quite helpful. Just had a small question. What are some typical inputs you need to know to execute this analysis. I can see that we need a PSD curve. What about input for RANDPS? There are 2 loadcases which are being used in RANDPS. Do we need to know those as well??

hmm.. RMS is a time duration of that particular g , so g * time
