thank for your reply, but  cellside: fixes the unit-cell side lengths to their initial values (not implemented yet). cellangle: xes the unit-cell angles to their initial values (not implemented yet). so my meaning 1. is that my consstr.f is right or not: 2. should i use MD.VariableCell =T ans we

Hi,all: i want to relax the geometry of the cell, but i only need relax the c cellside, and fix the a, b side. according to the manual; i rewrite the cinstr.f the code is *! and J.M.Soler, 1996-2006.* *! * *! Use of this software constitutes agreement with the full conditions* *! given in the S
