Ansys Workbench - Frequency Response

Hi,

How to obtain acceleration vs frequency graph? i use frequency response analysis, but frequency response does not let me apply rotational velocity load.

Is there any analysis that i can use in order to obtain acceleration vs frequency graph?

Acceleration of what? Frequency of what?

i am doing simulation of rotating propeller.. from the simulation, i need to obtain vibration data in term of acceleration versus frequency.. which type of analysis i should use?

Sounds like CFD plays no part. In this case it is a pure FEA simulation and can be done using FEA frequency analysis tools. If you need assistance doing this sort of modelling you better post on a FEA forum.
