I have input and output values in the time domain and I want to convert it to frequency domain to find frequency response functions. Then I used fft function in MATLAB to do that. I have 8192 data points from 24 locations which means dimension of acceleration matrix is 8192*24 and force matrix...

Hi all, I have input force data and output acceleration data to calculate frequency response functions. As these data are in time domain I converted it to frequency domain using fft function in MATLAB. This is the procedure I used. As an example Let's think, Force matrix =a Acceleration...

I want to get stiffness matrix and mode shape values from ANSYS software. Please help me.

I have time varying force. Is there any possibility to apply such type of load in harmonic analysis. I know transient analysis can do it. If load can't be applied in harmonic analysis, can I do transient analysis and is it possible to get FRF using MATLAB? Please help me.

Hi all, I want to get Frequency Response Functions from ANSYS software. Can anyone give me a guideline? Thank you.
