Converting spheres to polyhedral

Asked by Nima Goudarzi

Hi,

Is there any experience with converting deposited spherical particles in a container to polyhedral particles (anything built in yade or some programming). I need to study different degrees of angularities and compare the results with a newly implemented model which accounts for rough surfaces (some degree of interlocking)?

Thanks so much

Nima

Hi,

Are you interested in an instant, kind-of magic, transformation of YADE bodies with a spherical shape, into YADE bodies with polyhedral shapes ?
Or into a comparison of two simulations, one using spherical particles, the other using polyhedral particles ?

In case it's the 1st choice, I do not know any, and it's hard for me to imagine an exact logic for such a procedure.

Hi Jerome,

I think there might be a magic. Take a look at this: Discrete element simulations of direct shear tests with particle angularity effect. I have the paper but don't know how to attach here

They have converted spheres to polyhedral. If you know some ways similar to what is implemented in the article please let me know

Thanks so much,

NG
