Hello everyone, I am a student in mechanical engineering and I am making a simulation with flow les model around a tube counter. the problem is that in the analysis fft of the coefficients of portance (cl) and of resistance (cd) after at least 10000 iterations, I find on fluent the following message:
"warning: read_signal: fft can handle a constant sampling interval only!
jump in sampling at sample 3 is more than 1 percent!"
just load the cl and error notice:
"process_and_plot: negative time step!"
when I load the cd.
Am I wrong with sampling? or anyway, how do I behave?
I hope you can help me.
