<p style="margin-top:0;margin-bottom:0">This is definitely strange and not usual behavior.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">How are you increasing your resolution? Are you moving to a new mesh? Are you simply changing lx1 in the SIZE file?</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">How many elements are you using now and what order lx1 ?</p>

<div>Dear all</div>
<div><br>
</div>
<div>First, many thanks for your response. I couldn't be more thankful. </div>
<div>Either by starting with high Reynolds number or by using initial noise is working now. However, once I increase the resolution the turbulence decays and disappears completely, and I don't know why? I just wanted to make grid independence and my geometry
is very small, 10 cm in axial direction & 1 cm along the radius.</div>
<div><br>
</div>
<div>Any idea is greatly appreciable.</div>
<div>Ali</div>
