Jan Stránský proposed the following answer:
Hello,

using Jerome's hint:
###
def extractContacts():
    facets = [b for b in O.bodies if isinstance(b.shape,Facet)]
    interactions = [interaction for facet in facets for interaction in O.interactions.withBody(facet.id)]
    contacts = [(
        i.geom.contactPoint,
        i.phys.normalForce + i.phys.shearForce,
    ) for i in interactions]
    return contacts
###

Cheers
Jan
