<p class="MsoNormal"><a name="Gruß"></a>Hi,
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-US">I’m using gmsh for creating a finite element model of a full aircraft model for structural analysis.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">For that purpose, I have written a python process which writes the input geometry of the aircraft as .geo file and pass it to gmsh via a simple batch process in Python. My problem is that when I run that process in batch
mode, gmsh is running and produces some files called “before.msh” or “after.msh” again and again and seems not to converge the mesh generation.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">If I start the GUI of gmsh with the input geometry and start the mesh generation inside, gmsh finishes after around 4 seconds with a nice mesh!<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The aircraft is mainly defined by regular 4 point areas which I recombine to get quadrilateral elements. At some places due to the local aircraft structure definition, there are some areas with 5 lines which produces
some small degenerated elements.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I already tested different meshing algorithms and options directly written in the geometry input file to overcome to problem, but the batch process of gmsh doesn’t finish, though.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Can anybody help me with this problem?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Thanks in advance!<o:p></o:p></span></p>
