Contact Smoothing

Asked by bruna

Hello everybody!

Does anybody know if it is possible to smooth the contact between two particles so that it loses its angularity? I am trying to create a 2D circular particle gluing spheres and locking one of the free planes.

Thanks a lot in advance!

Bruna.

Hi,

The JCF model (see [*] and related classes) has a "smoothJoint" attribute that is useful (in rock mechanics, usually) to describe plane to plane contacts instead of sphere to sphere.

But I have to say, my understanding of your question is way too limited to guess if this is what you want....

In particular, how would some contact smoothing relate with 2D simulations ?....
For 2D simulations, you may basically just define all your particles centers to be in the same plane, and block appropriate degrees of freedom.
And you would end up simulating interacting 2D circles (with one circular particle = just one YADE body)...
