[Nek5000-users] 2D axisymmetric problems

[nek5000-users at lists.mcs.anl.gov]

Hi Mike,

In the 'axi' example, genbox produces an unnecessary line in the .rea file
when the .re2/.rea files are created.  If you delete the following line from
axi.rea, it should work:

 ***** NO THERMAL BOUNDARY CONDITIONS *****


We are working on the azimuthal velocity issue.

Thanks,
Katie
