<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am using the attached file to generate a geometry in Gmsh and finishing the 3D meshing process using the GUI. It creates a quadrant of a thick disk. There is an interior surface that I use to bias the mesh towards where I need the highest
mesh density. This works great for generating tet meshes. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have been advised that the particularly problem I’m studying (mechanical analysis of a system in compression) may perform better with hex elements. Therefore, I tried to generate a mixed but predominantly hexagonal mesh using the GUI
with the same geometry by changing the settings to recombine the 2D mesh into quads. However, I get errors because the surface is non-manifold. The internal surface I use to bias the mesh creates an edge with 3 contacting surfaces.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So my question is: how can I create a predominantly hexahedral mixed 3D mesh with a bias towards an interior surface without running into non-manifold surface errors? Can I bias the mesh without the interior surface? Can I delete the interior
surface between generation of the 2D mesh and the 3D mesh? Am I setting this problem up the wrong way?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any tips or thoughts would be much appreciated.<o:p></o:p></p>
