<p dir="ltr">You mean a ruled surface that isn't flat itself?</p>
<p dir="ltr">Recombine the mesh for that surface to get the quads. And pay attention to specify 1st order elements in the mesh options. If you want structured quads, check the documentation and the tutorials to get the transfinite lines and surfaces.</p>
<p dir="ltr">You should get a non-planar surface with flat first order elements.</p>
<p dir="ltr">Hope this helps</p>

<p>Dear Gmsh users,</p>
<p><br>
</p>
<p>I am working with ruled surfaces and at the end I would like to get a quadrangular mesh with only flat faces.</p>
<p>Is there a way to mesh a ruled surface with flat quadrangular faces?</p>
<p><br>
</p>
<p>Thanks,</p>
