<b>Subject:</b> [Nek5000-users] Restarting with Periodic boundary Condition</font>
<div> </div>
</div>
<div>
<div dir="ltr">Hello Neks,
<div><br>
</div>
<div>I have a small (4x4x1) cubic domain, which is periodic in Y. No slip boundaries in X and Z. This is to generate a Rayleigh Benard convection flowfield with Z being the convective direction. The flow is driven by hot sidewalls in X.</div>
<div><br>
</div>
<div>My problem is when I restart the flowfiled from a particular flowfiled file using the same .rea, .usr files and everything, the periodicity in the Y direction seems to be gone. </div>
<div><br>
</div>
<div>My originial flowfileds are periodic in Y and have the same value of Velocity Magnitude through all the Y slices ( as can be seen with VisIt). But my restarted files have different values of velocity magnitude in different slices of Y, which should not
be the case.</div>
<div><br>
</div>
<div>This seems to suggest something going wrong during restarting for the periodic bc side. I haven't noticed any change in the Velocity if I have no-slip in Y instead of Periodic.</div>
<div><br>
</div>
<div>I would appreciate any input on this problem.</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Saikat</div>
