<p class="MsoNormal">I would like to do a constraint surface mesh imposed by one geometry onto the next one.
<o:p></o:p></p>
<p class="MsoNormal">I am using Gmsh 4.4.1 and it crashes if I change the definition of one of the plane surface to a surface.

<p class="MsoNormal">The Duct. Geo is the file with the first geometry.<o:p></o:p></p>
<p class="MsoNormal">Coupling.msh contains the constraint surface mesh for the 2<sup>nd</sup> geometry<o:p></o:p></p>
<p class="MsoNormal">Liner.geo is the 2<sup>nd</sup> geometry where I import the Coupling.msh to impose the constraint mesh.

<p class="MsoNormal">The complete set up works fine if Line 37 in Liner.geo file is defined as plane. But actually this is a curved surface.
