I'm inserting superquadric particles in a closed box. I want to achieve different volume fractions samples.
First, I tried insert/stream command but I couldn't control volume fraction with it.
Second, I tried insert/pack and insert/region/rate but only low volume fraction can be achieved with both methods even with very high maxattempt values.
Finally I'm trying to insert particles with no overlap check using nve/limit for several steps then unfix nve/limit and fix nve/superquadric. But I found some particles moved accidently with high velocity after nve/superquadric is introduced which is improper behaviour and I think the reason is the existence of overlap between those particles.
My questions:
1) Is there another way to eliminate the overlap between particles after inserting them without the overlap check?
2) Does nve/limit works with superquadric particles? I saw another topic that says it only works with spheres?
3) What is the proper value of "Xmax" that is used in nve/limit?
4) Is there any other technique that can be used to insert superquadric particles with different volume fraction?
Appreciate any help!
