[lammps-users] Apply torsion in the cylinder

Hi, all.

I'd like to apply the torsion at the end of the cylinder and fix the other end to see the buckling behavior.

but I am not sure how to apply torsion and fix the end properly.

Is there anyone who did this kind of simulation?

Thank you,
Kyoungmin Min

You'd have to write a fix to do this.
