<div>Could you please help me to solve my problem? My geometry is axisymmetric with the following dimensions (R=0.01 m, L=10 R). Well, I did DNS and got something indicating turbulence which is consistent with experiments. However, once I increase either the
spatial and/or temporal resolution even a little bit, the flow is laminarized completely. </div>

<div>Any help would be greatly appreciated</div>
