Stones

Submitted by aharon.sanchez on Tue, 03/20/2012 - 10:58

Hello,

I am Aharón Sánchez, and I have a doubt. I want to modelize the behaviour of a group of stones (near 63 mm of diameter) when some vibrations are induced in them. Can anyone tell me if this is possible?
How can I model vibrations?

hi!

I guess vibration is not flow induced - so it seems to be a pure DEM (LIGGGHTS) topic.

Check that forum for more information.

Cheers,
Chris

Sounds like you need to include a sinusoidal vibration using the fix/move/mesh/gran with the wiggle option. For example,

fix vib all move/mesh/gran wiggle 0 0 0.010 0.1 cad1

See fix_move_mesh_gran.html for details.
