Fluent里FFT变换出现Warning提示:
Warning: Read_Signal: FFT can handle a constant sampling interval only!
Jump in sampling interval at sample number 5 is more than 1 percent!
不知道这个怎么消除,对结果有什么影响?请高手指教!
I found this error
Warning :Read_Signal: FFT can handle a costant sampling interval only! Jump in sampling interval at number 30 is more than 1 percen ! what does it mean ???
it means that your interval is very small. try increasing it, then u probably get your plot right.
You mean Data sampling for time statistics ( sampling interval)or where ??
i mean when u go to axes, then u can select the interval of plotting. i had the same problem, and when i increased this interval of ploting(the range), it worked.
