Question #237437 on Yade changed:
https://answers.launchpad.net/yade/+question/237437

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi Felix,

probably nobody needed this feature before, so it was not there :-) I have
changed the code such that the CombinedKinematicEngine will not call its
subengines iff their dead attribute is set to true. Could you please update
to the newest version and try it?
cheers
Jan
