[Nek5000-users] Genmap Error?

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

What you see is not related to MAXNEL otherwise genmap would bail out with an error message.

Hi!

Maybe you should increase MAXNEL parameter in maketools script (Nek5000/tools)?

Hello,
I created a ".re2" mesh by converting an Exodus (".exo") mesh from Cubit 
15.0 using the "exo2nek" script. It's a relatively large mesh (780k 
elements) and I need to run it using parallel processing, and so I 
wanted to use the "genmap" script.

However, I keep getting these errors, no matter what input mesh 
tolerance value I use, from 0.2 to 0.00001):

genmap
Input .rea / .re2 name:
RCF_3D_FullSimple
  reading RCF_3D_FullSimple.re2
Input mesh tolerance (default 0.2):
NOTE: smaller is better, but generous is more forgiving for bad meshes.
0.00001

Do you have any idea what this means? Just from the output, it looks 
like it's saying there are coincident vertices or elements? Is it a 
problem with my mesh or with running the script?

Thanks,
Matt
