I am trying to study strain (uniaxial,hydrostatic) effects on radiation damage in HCP Zirconium. as we know in Zirconium miller indices are "[hkil]" where "h+k= -i". so how can i apply hydrostatic strain. As for example in lammps we can apply hydrostatic strain by fix deform command.
fix 2 all deform 1 x erate 0.005 y erate 0.005 z erate 0.005 units box remap x
then how would be interpenetrated this Kind of strain command?
