<p class="MsoNormal"><span style="COLOR: #1f497d">Meshing worked fine after selecting the option you specified. However, when I tried the same thing with a more complex problem (e.g., lots of curved surfaces), I got the following error while opening the STEP

<p class="MsoNormal"><span style="COLOR: #1f497d">then I got again intersecting surfaces errors while meshing. Could the curved boundaries be the cause?<o:p></o:p></span></p>

<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have quick question regarding the meshing of compound volumes.<o:p></o:p></p>
<p class="MsoNormal">I have a simple geometry, basically two cubes stacked together and sharing one face. If I fuse the blocks, then there is only one volume and meshing works correctly. However, if I export as a compound volume, so two volumes sharing one
face, Gmsh gives loads of errors. Is there a way to mesh such compounds in Gmsh?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for your time,<o:p></o:p></p>
