Question #245072 on Yade changed:
https://answers.launchpad.net/yade/+question/245072

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,

check the script from Klaus, there is

ids = facets # list of facets

instead of your

ids = facet # which is actually a function utils.facet

cheers
Jan
