Two-dimensional periodic tessellation in raster format cannot be meshed

[dilekguzel]

Hello,

Neper cannot mesh a two-dimensional periodic tessellation in raster (.tesr) format. I believe problem is due to periodicity.

$ neper -T -dim 2 -n 10 -periodicity all -format tess,tesr -tesrformat ascii
I can create the tessellation in .tess and .tesr format, and can mesh .tess file without any problem, however it is not possible to mesh .tesr file, I have added a MWE. (I have also tried different examples and the error keeps showing for periodic case)

$ neper -T -dim 2 -n 10 -periodicity all -format tess,tesr -tesrformat ascii
$ neper -M n10-id1.tesr
