Hi Neks,<br>
<br>
I am trying to use n2to3 to create an axisymmetric mesh. I have created a 2D mesh using gmsh and it works. Now, the idea is to extrude the 2D mesh to create a tube (circular sweep). However, n2to3 doesn't seem to work.<br>
<br>
In the 2d file the geometry is rectangular with SYM boundary conditions in the x axis. Is it possible to use n2to3 to create the tube, or half of the tube? If it is possible what are the files that I need? I suppose that with the gemoetry_2d.rea file should be enough, shouldn't it?<br>
<br>
I realized that:<br>
<br>
If I set the number of planes to, let's say -10, and<br>
input z min:<br>
0<br>
input z max:<br>
90<br>
<br>
I have problems with genmap<br>
<br>
NOTE: smaller is better, but generous is more forgiving for bad meshes.<br>

Try to tighten the mesh tolerance!<br>

<br>
However, if I increase the number of planes, let's say -80, it seems that genmap also works. But, when I run the numerical simulations and I try to plot some snapshots, I cannot see anything. It seems that there is a problem with the connectivity. What I am missing?<br>
<br>
Thanks in advance.<br>
