Hi Neks,<br><br>I'm having a little trouble with my first foray into circular geometries. I tried to construct a 2D annular mesh using genbox with the following .box file:<br><br>-----------------------------------------------------------------------<br>
an.rea<br> 2 spatial dimension<br> 2 number of fields<br>Y<br>-4 -12 nelr,nel_theta<br>0 0 x0 y0<br>ccbb<br>1 2 1<br>0 1 1<br>SYM,SYM, V bc's ! NB: 3 characters each !<br>
f ,f , T bc's ! You must have 2 spaces!!<br>
-----------------------------------------------------------------------<br> <br>genbox seems to work properly, with the exception of the fact that nothing after the boundary data gets copied over from the old .rea file. Nonethess, I copy that chunk over manually and run nek5000, which exits with the following error:<br>
<br> WARNINGa: Detected non-right-handed element.<br> Number 1 C1-4: 0.6667E+00 0.8333E+00 -0.2083E+00 -0.4167E-01<br><br><br>Any guidance would be much appreciated.<br><br>Best,<br><br>David<br>
