How to get cauchy stress

Submitted by citizen erased on Wed, 04/27/2016 - 17:15

Hi everyone,

I am trying to model a cone penetrometer test (CPT) in a volume of sand and I would like to compute cauchy stresses in order to get shear lines but I can't find a way to do that. I don't think that the command compute/stress gives that kind of results.

Is there a way to compute them using Liggghts?

Regards,

Abdellah

Hi Abdellah,

well I think compute stress/atom does what you want.
But you can try fix ave/euler, too.
