Hi gmsh community;
<div><br>
</div>
<div><span style="font-size: 12pt;">Iīm trying to define a 3d mesh of a merged .brep surfaces for my PhD, to use it into freefem++</span><span style="font-size: 12pt;">.When I set opencascade geometry kernel, at the first line , surface loop creates duplicates
entities, and the subsequent volume is defined with this entities</span><span style="font-size: 12pt;">. However, the 3d mesh is seems to be correct, but the 2d mesh has overlapping faces, and when import this into freefem I got errors.</span><br>

</div>
<div>If I donīt use the opencascade kernel, The 2d mesh was made properly, however when apply the 3d mesh button, gmsh gives the error ". </div>
