Problem in forming a cubic with aligned particles

Submitted by z3490628 on Wed, 08/30/2017 - 12:05

Hi all,

I wish to insert particle into a 100*100*100 cubic. I would like to form the figure as attached with particles are settled under gravity and align with each other. (the one with blue particles) However, I couldn't able to form it and particles distribution are not similar to a cubic shape. (the one with grey particles) I have attached the figures and my script. Thanks for the help.

Using your input script (and changing custom/vtk to custom since I did not install with vtk support...), I was able to get the cubic structure as seen in the first figure.

How are you running this simulation? Running in parallel?

It may just be failing to find a place to insert a particle, so you may wish to increase the number of times a particle will be attempted...

Hi mschramm,

I used to command liggghts < in.cubic to run my stimulation.

Are you using paraview to observe the result?

For increasing the number of times a particle will be attempted, can you please provide more details on this? I'm still a new user on Liggghts.

Thanks
