Question #185098 on Yade changed:

Status: Open => Answered
Jan Stránský proposed the following answer:
Hi Rinaldi,
as I see it, the script does not work, because (as error says) _eudoxos
is not defined. Try to use eudoxos instead (without underscore).
Hopefully you will be successfull.
If you have any other problem, do not hesitate to ask on this forum
Good luck
Jan
