Hi

someone can tell me what dimensions work wear? (for example [mm / year]) please

Regards.

Hello everybody,

Do you know where I can find the download folders in paraview plugin tab? I need the src_reader and src_bin reader. These are not in the download section.

Regards,

David

Hi all,
is it possible to set conductivity through a set property/atom? if not, where should I start coding? is it difficult?

thanks for your attention

Hi,

I am a little bit new LIGGGHTS and am trying to create a simulation of multisphere rigid bodies rotating in a cyllinder. However, after researching I am still very confused as to how the fix rigid command works.

How does one combine particles into a group to be 'fixed rigidly'?

Any help in this matter would be greatly appreciated!

Thanks!
Quincy

Hi All,

Fix rigid/small behaves very differently than fix rigid in v3.0.1. It seems like rigid bodies created by fix rigid/small can exert forces on neighbor particles, but the rigid bodies themselves do not move at all. For some reason, it looks like bodies created by fix rigid/small are not being time integrated. In the source code, the integration schemes look the same... Anyone have the same experience?

FYI, my comm cutoff is large enough, I have tried several comm cutoffs with no change in results.

Thanks,
Zamir

EDIT: Attached a test case

Hi

i like to use a lognormal distribution but the ERROR message says this is currently deactivated
is there a chance to activate this distribution?

thanks

Hi,

I am a new user of LIGGGHTS and I need it only for generating a 3D packing geometry. The 3D packing consist of a cube with five different particle sizes. I am dealing with two issues.

Hi all,

According to the doc pages for dumping the forces on the walls the command "fix mesh/gran/stressanalysis" should be used.

My problem is that I have imported the walls by "fix mesh/surface" and changing it to "mesh/gran" didn't work (got the error: invalid fix style)

It seems to me that "fix mesh/gran/stressanalysis" works only if you have used the "mesh/gran". So I was wondering what do you suggest for dumping the forces on the walls without changing the importating command?

Thanks in advance,
Danial

Hi all,

I use "pair_style none" to turn off the particle interaction.

But it reports the following error.
