[Yade-users] [Question #696598]: Deactivating NewtonIntegrator.gravity on just a group of particles in the model
New question #696598 on Yade: https://answers.launchpad.net/yade/+question/696598 Hi everyone! In just a few particles of my model, I would like to keep the dynamics, but without the gravitational force on these elements. I mean, I wonder if it's possible to do this by turning off gravitational acceleration (NewtonIntegrator.gravity) on just a part of the model's elements and at the same time having gravitational forces acting on the rest of the model's particles.

New question #670352 on Yade: https://answers.launchpad.net/yade/+question/670352 Hello everyone! I am interested in the Sphere-GridConnection and Sphere-PFacet contacts. The problem is that I can not have the two wrappers 'Ig2_Sphere_PFacet_ScGridCoGeom' and 'Ig2_Sphere_GridConnection_ScGridCoGeom' together with the law 'Law2_ScGridCoGeom_FrictPhys_CundallStrack()', as this returns me an ambiguous dispatch error (I am using Yade 2018-02-05.git-243ee13).

In the simple script below [please, use it however you want ;-)], after using a comment mark in the law 'Law2_ScGridCoGeom_FrictPhys_CundallStrack()', do the forces calculated in the GridConnections are divided and applied in their two GridNodes?
