<p class="MsoNormal"><span lang="EN-US">I experience difficulties creating a pure or at least Hex-dominant mesh for the model in the text file. I tried a lot of solver options but even with the frontal algorithm and AllHexas subdivision algorithm I cannot get
a proper mesh. Volume elements are only created for the left and right volume while the boundary surfaces of the middle volume are meshed but no volumes are created and different errors are thrown by gmsh, e.g.<o:p></o:p></span></p>
