Multi-sphere method and non-spherical particles

Submitted by andybond13 on Fri, 05/24/2013 - 17:17

Hello,

I'm interested in exploring the capabilities of LIGGGHTS for generation of multi-spheres and simulation of non-spherical particles (using multi-spheres). Where can I find more documentation on LIGGGHTS capabilities for these subjects?

Thanks,
Andy

This is not in the public release. Please see fix rigid for existing functionality in the public release

Hi Srdjan,
this is not in the public release. In the next few months, we will make a major update of the website, denoting clearly which features are in the public version

Cheers
Christoph

Hi,
I am interested in simulating non-spherical particles (using multi-spheres) too. If I had understood, the public release of LIGGGHTS does not offer this capability. Is it right? Will it be included with the new release of LIGGGHTS 3.0.0?
Thanks.
Best regards,
Ferdinando

Hi,
is there anyone who can answer me? I'd like to know about that feature.
Thanks to all.
Best regards,
Ferdinando

What I have found that you can do is to use the hybrid granular and molecular packages. Each single sphere is an 'atom' and each grouping (non-spherical particle comprised of spheres) is a 'molecule'. The 'fix rigid molecule' command will integrate each molecule as a unit.
