Status: Open => Answered Jan Stránský proposed the following answer: Hello, > 1.- Generate a cylinder and deposit the grains inside. This has an associated stabilization time in which all the particles settle and the system is at rest. See e.g. [1] for a library function - facetCylinder instead of facetBox: ### cylinderFacets = geom.facetCylinder(...) cylinderFacetsIds = O.bodies.apend(cylinderFacets) ### Or you can create your own solution, e.g. using boxes or pfacets instead of facets. > 2.- Once this happens (i.e., all the grains stop), I remove the cylindrical container and allow the granular column to flow. Use O.bodies.erase [2] ### ... O.run(10000,True) # run 10000 steps. Or some stop condition. Or ... In case of this problem, pleas open a new question for f in cylinredFacets: O.bodies.erase(f.id) # or # for i in facetCylinderIds: # O.bodies.erase(i) ... ### Concerning the flow, have a look at recent discussion about "rectangular" results [3].
