Hi Christoph,
I found that LIGGGHTS can not dump stresses on the CAD cylindrical wall properly when the ratio of the diameter of beads to the diameter of cylinder is bigger than 0.02; however, below this ratio, the stress profile is good. But, using this low ratio is computationally expensive. Is there another way to do so?
Thanks,
Ram

what do you mean with "can
what do you mean with "can not dump stresses on the CAD cylindrical wall properly"?
A problem with the code, or with statistics?

statistics- there are huge
statistics- there are huge fluctuations in curves when that ratio is high, however, finer curve is obtained with lower ratios

a periodic BC of type "wegde"
a periodic BC of type "wegde" would be a solution which would give a speed-up of ~5-10 for this.
but this is quite tricky - someone with sounds knowledge of the code would have to code this
