Question #696056 on Yade changed:
https://answers.launchpad.net/yade/+question/696056

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,

assign mass (and inertia, depending on your needs [1]) to the facets
###
f1=facet(vertices=[(0,0,0),(0,1,0),(1,0,0)],wire=False)
f2=facet(vertices=[(1,1,0),(0,1,0),(1,0,0)],wire=False)
f1.state.mass = 1
f2.state.mass = 1
O.bodies.appendClumped((f1,f2))
###

Do you need a clump for the boundary?
Why are Individual facets not suitable?

Also next time please provide more information, e.g. Yade version [1] (I
have some older versions, which does not produce the error)

cheers
Jan
