Regarding the output of dissipated energy in granular simulation

Submitted by toto88 on Wed, 07/19/2017 - 20:46

I can see from the new version of LIGGGHTS that dissipated energy can be tracked. Can anybody help me in how to dump the dissipated energy. Thanks in advance

computeDissipatedEnergy values = 'on' or 'off'
on = the normal model saves the dissipated energy for each contact for the
use in fix calculate/dissipated_energy

Hi,

this is a premium feature and not available in the public version of LIGGGHTS.

Dear Arno thanks. Is there any way to do the same .Like I was trying to dump dissipated_energy into fix property/atom
but it is showing an error ''there is already a fix that registers a variable of the same name''.
I think in the code it is calculating the dissipated energy and then it is outputted to fix calculate/dissipated_energy. Am I correct on this?

thanks

HI,
Can anybody help me how to find total number of slip events in a time step in granular simulation.
I tried adding a counter in pair_gran_hooke and also a compute flag in compute/pair/gran/local. But it is not working. Can anyone help please.
