Re: [Question #683388]: How to clump spheres and facet obtained from stl format
Question #683388 on Yade changed:
Status: Open => Answered
Jan Stránský proposed the following answer:
> Is the pack.randomDensePack function appropriate for this situation?
if you do not need precise particle size distribution, then
randomDensePack is one option
> Any rule of thumb in deciding the sphere radius?
no, depends on your needs
> Does the function include overlapping of spheres?
no. But you can then enlarge the spheres to create overlaps
> By adding memoizeDb='/tmp/gts-packings.sqlite', does it mean that a
temporary sqlite file will be created to store the packing that will be
yes. The next run, this packing is read and is not generated again
 Is there any function to obtain the clump volume as comparison to
the imported gts surface.
> When running the script, I received the following error along with a blank view (no sphere or surface):
> WARN /build/yade-fDuCoe/yade-2018.02b/pkg/common/InsertionSortCollider.cpp:242 action: verletDist is set to 0 because no spheres were found. It will result in suboptimal performances, consider setting a positive verletDist in your script.
It is not error, but warning. Not inportant for now
To help you more, we would need a compete script and all data (i.e.
sample.gts file). For testing purposes, a simple tetrahedron should be
enough. So please provide the data to help you more.
