Jan Stránský proposed the following answer:
Hi,
@Robert
###
O.bodies.append((sphere((0,0,0),1),sphere((1,0,0),1)))
O.engines = [
ForceResetter(),
InsertionSortCollider([Bo1_Sphere_Aabb()]),
InteractionLoop(
[Ig2_Sphere_Sphere_ScGeom()],
[],
[],
),
NewtonIntegrator(),
]
O.step()
###
terminate called after throwing an instance of 'std::runtime_error'
what(): Undefined or ambiguous IPhys dispatch for types FrictMat and
FrictMat.
Aborted (core dumped)
@Vincent
in general it would be possible, but I don't think easily with current
implementation (haven't tried, thought). E.g. Interactions without IPhys are
normally treated as non-real, I am not sure with consequences for your use
case..
Would setting zero stiffness to materials be ok for you? Then the force
computed would be zero and forces would be applied exclusively from what is set
to O.forces..
cheers
Jan
