Hi Henry,

there are more possible approaches. It depends on purpose and what you
expect.

1) The approach you already mentioned (for loop oved all interactions), but
you have to change parameters which are defined on the specific IPhys
(CohFrictPhys [1] in your case, but you tried to change parameters that do
not exist). In some IPhys, as Klaus mentioned, not all parameters are
modifyable.

2) change material of all particles, but then you have to delete and
recreate all interactions, e.g.:

pairs = [(i.id1,i.id2) for i in O.interactions]
for b in O.bodies: b.mat = newMat
O.interactions.clear()
for id1,id2 in pairs: utils.createInteraction(id1,id2)

this will preserve also cohesive bonds, but delete all internal variables
of the bonds

cheers
Jan
