Hai,
I know that analysing the parts in frequency domain is the most desired one, because it can be related to its natural characteristics by their modal frequncy.
In one of my structure under operating conditions, I noted down the inside gas pressure versus time data. I converted the same into frequency domain, in the form of pressure versus frequency using FFT functinality. This input data, I am using it as a loading condition for numerical simulation of the displacement response using harmonic response analysis(i.e in frequency domain).Then the displacement response data will be converted into time domain using inverse FFT functionality.
I had confusion in the above problem if it is solved using transient analysis, what difference it will make?
Whether I will be getting the same results as the above one?
I am using ANSYS6.1 with SGI,octane 512MB ram and 40GB HDD
With Thanks and regards,
