<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am working on a fairly complicated 3D model and mesh using gmsh that requires OpenCascade (for Boolean operations mostly). I have been running into some odd issues near some of the edges which I originally thought might be overcome by
modifying my Boolean operations. However, after quite a bit of testing I found the problem occurs for even a simple script:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">SetFactory("OpenCASCADE");<o:p></o:p></p>
<p class="MsoNormal">Mesh.CharacteristicLengthMax = 1.0;<o:p></o:p></p>
<p class="MsoNormal">Cylinder(1) = {0, 0, 70.0, 0, 0, 60.0, 50.0}; <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I set all of the gmsh options to their defaults except for viewing element faces and you can see the resulting image attached. I finally discovered that this does not occur in version 3.0.6 of gmsh but it does occur in version 4.0.4.
Have you seen this behavior? I presume this is a bug or there is a flag of some kind that I need to set?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<br>
