<div>Dear Neks,</div><div><br></div><div>Recently, I am trying to set up a linear stability analysis of flow past a cylinder at very low Re, see Re=20, after I had a converged base flow, I modified the example “lin_chan*” and read the dns result as baseflow and updated the *usr file, after testing groups of parameters in *.par, I obtained different groups of growth rates, but none of them is closed to the value documented by Luchini et tal, JFM or the value given by other codes. Are there more details or rules to choose the parameters when performing a linear stability, e.g. Krylov space dimension, number of converged eigenvalues to be dumped?</div><div><br></div><div>Thanks!</div><div>Wei</div><blockquote id="ntes-iosmail-quote" style="margin:0"><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr">
