Hi i want to relate pressure with efficiency in cfx post.I want to draw a chart relating pressure with frequency .I am doing transiet analysis.I have to get pressure at each frequency.In trasnsient analysis post the chart can be drawn only for time on x axis.I want frequncy instead of x frequency.How i can do this.Can anybody tell me that?Thanks in advance.

How do you define frequency? You may create a variable in Post to get what you want.

A Fourier Transform is needed to transform data in time domain into frequency domain. I believe Post does not have this capability right now. You probably need a separate FFT code to do it.

It should be possible to write a small program for fft analysis and run it under command window.
If you have other software like Matlab, just export your data into a text or csv file. |
