<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">I'm trying to implement outflow boundary conditions for a turbulent plume using a sponge layer to absorb the energy of the flow and prevent reflections back into the domain. I was wondering whether there is anything
set up in Nek already to construct this sponge layer or if it's something I need to do myself, and if so whether anybody could help with something they've done before - I've read a couple of other threads here that mention a sponge layer but not its implementation.</p>

<p style="margin-top:0;margin-bottom:0">I look forward to hearing from you.</p>
