Hi Behzad, you have more options:
1) use O.bodies.appedClumped(facets) to create a clump, which you can aplly force to. Currently it does not work with facets, but it should not be difficult to make it work with non-spherical shapes. I don't have time now to work on it.. 2) use normal bodies and use RotationEngine on them, each (or each a few) time step checking forces on individual facets and apdate angular velocity according to the value (i.e. creating PyRunner doing the same as NewtonIntegrator :-) I like no 1 most (if it works), you can ask some other developers for the help :-) cheers Jan 2015-02-01 20:36 GMT+01:00 behzad <[email protected]>: > New question #261529 on Yade: > https://answers.launchpad.net/yade/+question/261529 > > > Hi, > > I need to create(or import) a cylindrical-shape body and as I see in any > case this cylinder is presented by an assembly of facets which means > several bodies. > > However, what I want to do is measuring the viscosity of a material.
