[Nek5000-users] prex output - curved side data

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

Dear Neks,

the rea files written out from prex mesh generation module contain a block entitled 

******curved side data******

which contains edge and element indices.
My question: which information contains the array curve (i), i=1,5 which is listed in the columns afterwards?

Thanks in advance and best wishes, Joerg.
