[Nek5000-users] Periodic BC & Genmap issue

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

Hi, 

I am running into an error when trying to use genmap. I believe it has to do with the periodic boundary conditions I have set up. I have checked the elements, and faces and indeed they are given correctly. This leads me to believe that there may be an issue with genmap. I have attached the rea file. This was to test the periodic faces for this geometry. The output is shown below, thanks for any help with this.

Here is the output:

NOTE: smaller is better, but generous is more forgiving for bad meshes.
