[Pw_forum] coordinate system for forces when positions are in "crystal" coordinates

[Murray Daw]

Are the forces always calculated in cartesian coordinates?

Specifically, when the positions are given in “crystal” coordinates, are the forces in
cartesian coordinates or “crystal” coordinates?

Thank you.
