Re: [Question #259263]: Decrease bond strengths to make a model collapse

    Status: Open => Answered

Jérôme Duriez proposed the following answer:
Yes, this is exactly what you have to do. Looping over interactions to reduce CohFrictPhys.shearAdhesion
(it would read something like
for cont in O.interactions:
  cont.phys.shearAdhesion = something lower
)

Because this is this parameter that controls the shear strength of contacts, see 2d paragraph of the doc of the Law2 you're using:
