> Dear Nek Users,
> We are about to set up a new case with about 29692 in 2D, which we
> would like to extrude to about 150 elements in 3D, giving a total of
> about 30k times 150 = 4.5M elements. n2to3 works fine, but genmap
> gives a "periodic mismatch error". Having a lower number of extrusion
> elements, say 30k times 70 = 2.1M elements, works fine. Changing the
> tolerance in genmap does not fix it.
> 
> Before diving into the code of n2to3 and genmap, we wanted to ask
> whether somebody has experienced that before, and whether you'd know a
> potential fix for the problem.
> 
> We used both an older version of genmap and the latest github version.

> Thanks a lot!
