<p style="margin-top:0;margin-bottom:0">Hello:</p>
<p style="margin-top:0;margin-bottom:0"><br>

<p style="margin-top:0;margin-bottom:0">I have a simple test case where smoothing does not work as I expected, maybe there is a reason.</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">I have two surfaces, one unstructured (surface 2) and other structured (surface 1) (transfinite using progression 2)</p>
<p style="margin-top:0;margin-bottom:0"><br>
</p>
<p style="margin-top:0;margin-bottom:0">With <span>Mesh.Smoothing=0 all is ok (transfinite surface using progression does not</span> lose any anisotropy)</p>
<p style="margin-top:0;margin-bottom:0"></p>
<div>With <span>Mesh.Smoothing=1 the unstructured surfaces is smoothed (improved ICN quality) and transfinite surface using progression does not</span> lose any anisotropy</div>
<div>With <span>Mesh.Smoothing=2 the transfinite surface using progression loses anisotropy, that is, it tends towards "uniform" or progression 1.</span></div>
<div><span><br>
</span></div>
<div><span></span>I found a workaround using <span>Mesh.Smoothing=2</span> and <span>
Smoother Surface {1} = 0</span> (as Smoother Surface is only for transfinite surfaces but I dont see how it cannot apply to non-transfinite surfaces)<br>
</div>
<div><br>
</div>
<div>In conclusion, I would expect that <span>Mesh.Smoothing</span> applies to all surfaces at any value and not a selective behaviour at value 1 (maybe is a design feature as gmsh default value of it is 1). Additionally, I would expect that Smoother Surface
applies to all surfaces and not only to transfinite.<br>
