<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Dear Gmsh team,
<div><br>
</div>
<div>I will try to keep this as concise and descriptive as possible. I am quite new to this meshing software.</div>
<div><br>
</div>
<div>My problem is this: I am trying to build a 3D mesh in gmsh script files (.geo). When I try to generate the 3D mesh I receive an error that informs me that I have intersecting surfaces. I understand where the intersecting surfaces are and why gmsh is complaining;
this is not the problem. The problem is, I don't see how I can avoid having intersecting surfaces to achieve the geometry that I need.</div>
<div><br>
</div>
<div>I have attached a screen shot of the geometry: I hope you can see that it is simply a rectangular prism, with a smaller rectangular prism extending outwards from one of the sides. </div>
<div><br>
</div>
<div>Obviously, the two rectangular prisms have an intersecting surface, but this seems unavoidable? Is there no way to create a mesh for the entire volume as a whole?</div>
<div><br>
</div>
<div>If it is any help: I need to have two separate physical volume groups so that I can assign each different material properties. I just don't see how I can create the two distinct volumes that I need without a common intersecting edge?</div>
<div><br>
</div>
<div>I hope my problem is clear. Any help would be appreciated.</div>
<div><br>
</div>
<div>Thank you,</div>
<div><br>
</div>
