WebSome techniques that seem to help are (a) use the “min_modify line quadratic” option when minimizing with box relaxations, (b) minimize several times in succession if need be, to drive the pressure closer to the target pressure, (c) relax the atom positions before … WebThe fix box/relax command can be used to apply an external pressure to the simulation box and allow it to shrink/expand during the minimization. Only a few other fixes (typically those that add forces) are invoked during minimization. See the doc pages for individual fix commands to see which ones are relevant. Current examples of fixes that ...
