I have some bulk system and want to calculate elastic constants (C11, C44,C13). The examples/elastic directory contains example input scripts. I have modified init.mod and potential.mod keeping the input script unchanged. After running it I’m getting the following error : ERROR: Cannot change box tilt factors for orthogonal box (…/change_box.cpp:251).

Can you give me some hints how to solve this and generate the elastic constants.

Thank you

box tilt factors for orthogonal box (../change_box.cpp:251).

constants.

your initial box box is orthorhombic, but should be triclinic with

tilt factors 0.0 0.0 0.0.
