Hello,
I am trying to study the effect of mechanical vibrations on a linear-elastic tube with a certain fluid flowing along it. how can i couple the mechanical structure with the applied vibrations to fluid structure and perform FSI analysis.
Hello Mr. Marandi,
I am currently using ANSYS with student license.

Here are the steps you can follow:
Berkay Sarı Thank you for your answer,
I have managed to set up The model. However, regarding the mechanical vibrations I have only managed to input the data as tabulated time-pressure readings. I would like to study the system at different frequencies and frequency bands. I have time domain data collected from a pressure transducer as well as the power spectrum of for 3 one-minute sequences of the transmitted vibrations on the wall of the tube structure. Is there a way i could input the vibrations as a power spectrum ?
Thank you in advance,
Fares.

Yes, it is possible to input vibrations as a power spectrum instead of time-pressure readings. This approach is known as random vibration analysis, and it is commonly used in structural analysis and FSI simulations to model random vibration inputs such as those encountered in real-world applications. Here are the steps you can follow to input the vibrations as a power spectrum:
Converting the power spectrum to a time-domain signal and applying it as input to the FSI simulation is a common approach for modeling random vibrations in FSI simulations. By following these steps, you should be able to input the vibrations as a power spectrum and study the system at different frequencies and frequency bands.
