[Nek5000-users] help: 3d revolved mesh

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

Hi,

Looking at the error message, it seems there is something wrong with the
source file, coaxJets.rea.  n2to3 is having trouble reading the curve data,
so I would suggest looking there to see that everything looks as expected.

After the mesh data, coaxJets.rea should have something like:

  ***** CURVED SIDE DATA *****
           0 Curved sides follow IEDGE,IEL,CURVE(I),I=1,5, CCURVE
  ***** BOUNDARY CONDITIONS *****

It is important for the number of curved sides to match the number of lines
following it.  In this example it is 0, so there are no lines following.


If this doesn't solve your problem, please send me the coaxJets.rea file
off list to: heisey at mcs.anl.gov
and I will take a closer look.

Best,
Katie
