New question #691976 on Yade:
https://answers.launchpad.net/yade/+question/691976

Dear all, 
     I'm try to study how to create a PFacet with the "yade.gridpfacet.gtsPFacet" function. When I run the example in yade, it appears some errors. The script of the example is as follows,
#
from yade import qt
from yade.gridpfacet import *
import gts, os.path, locale

locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')   # Note: gts is locale-dependent. If, for example, german locale is used, gts.read()-function does not import floats normally

'''
if you get "Error: unsupported locale setting"
-> type as root: "dpkg-reconfigure locales"
-> choose "en_US.UTF-8" (press space to choose)
'''

I copy the script into yade and run it, the errors appear:
#
Traceback (most recent call last):
  File "/usr/bin/yade", line 336, in runScript
    execfile(script,globals())
  File "/usr/lib/python3/dist-packages/past/builtins/misc.py", line 87, in execfile
    exec_(code, myglobals, mylocals)
  File "718.py", line 60, in <module>

  File "/usr/lib/x86_64-linux-gnu/yade/py/yade/gridpfacet.py", line 382, in gtsPFacet
    surf=gts.read(open(meshfile))
FileNotFoundError: [Errno 2] No such file or directory: 'octahedron.gts'
#

It reminds me there is no  'octahedron.gts' file.But I don't  know how to create this kind files. If there is anybody knowing about this, could you teach me how to create the gts files and show me an example?

Many thanks!
