<p>Hi Amitvikram,</p>
<p><br>
</p>
<p>I'm guessing you can build this case with genbox, which allows you</p>
<p>to assemble several boxes together, each having varying resolution.</p>
<p>The boxes need to match in a conforming way, but this is not difficult.</p>
<p>You presumably could build a 2D mesh first, then extrude with n2to3.</p>
<p>Or you could build the 3D mesh directly with genbox.</p>
<p><br>
</p>
<p>In the span wise direction you can have periodicity, symmetry, or walls.</p>
<p><br>
</p>
<p>You can either use synthetic turbulence at an upstream inlet or you</p>
<p>can use a recycling BC that effectively gives you periodic channel flow</p>
<p>to generate incoming fully-developed turbulence.</p>
<p><br>
</p>
<p>Once generated, you probably want to apply a mesh smoother</p>
<p>before starting the simulations. We've found that this can improve</p>
<p>accuracy and reduce time to solution.</p>
<p><br>
</p>
<p>If you want assistance, feel free to email me off-list.</p>
<p><br>
</p>
<p>hth,</p>
<p>Paul</p>

<div>Hi all,<br>
<br>
</div>
I'm trying to use do a LES study of a plane jet exhausting into a domain in nek5000. I'd like to know which geometry in the examples folder is the closest to my needs.<br>
</div>
I suspect its the turbchannel one, but I'm not quite certain as to how to set the boundaries of the jet body as solid, within the domain.<br>
<br>
<br>
</div>
Sincerely,<br>
