https://answers.launchpad.net/yade/+question/707870

    Status: Open => Answered

Jan Stránský proposed the following answer:
Hello,


to get interaction of specific body, use [1]:
bodyIntrs = b.intrs()


To get interaction of multiple bodies, do:
bs = [bottom1,bottom2] # for example, bottom1 and bottom2 are bottom facets
intrs = [i for b in bs for i in b.intrs()]

# make them without possible duplicates
ids = set([(i.id1,i.id2) for i in intrs])
intrs = [O.interactions[id1,id2] for id1,id2 in ids]


Cheers
Jan
