multisphere partilce - limit motion

Submitted by Neiht on Fri, 04/05/2019 - 15:15

Hi all,
Im currently using LIGGGHTS to simulate the multisphere particle system. However, there are some difficulties in sample generation because of high Young modulus.
My question is: are there any functions similar to nve/limit to restrict the motion of particles within an expected value?
Thank you!

as far as I can tell you not. You would have to implement it in FixMultisphere::initial_integrate and FixMultisphere::final_integrate but should not be very difficult.
