Question #185098 on Yade changed:

    Status: Open => Answered

Jan Stránský proposed the following answer:
The problem is, that at the time of InteractionLocator construction, you
have no interactions present in the simulation. Try to place the command
to the time, where you have some. Also attach your script, so we can
advise a correct location to place the line.
