Hello, I’m encountering an issue in LAMMPS where voids are forming in my model during simulation. Could these voids be generated during the minimization iterations? Should I modify the dmax parameter, extend the minimization duration, or are there other specific factors causing this void formation?

Ok I’ll edit my post.
You did, but not for the better.
Could be.
Modifying the minimization parameters does not change the physics of your calculation.
Vacuum bubbles usually appear when the density imposed by the size of the simulation cell and number of atoms is in conflict with the force field (parameters). This can be due to an incorrect initial geometry, or corresponding box size, or due to use of a force field or individual parameters that result in a denser geometry.
