I agree that it is probably more common to define "external work input" as an input to the sample, yet overall it remains a matter of taste. I'm not for discussing/changing such sign conventions unless they are obviously wrong. There are probably tons of user scripts which would have to be adapted after such change (including mines), not a good thing. Instead, I would clarify the documentation without changing the code.

I would like it corresponds to the "Energy provided by boundaries" as the doc says, however it seems to me it's currently rather the energy provided to the boundaries (by the sample). Since we use the Force acting on the boundaries together with the boundaries velocities. Agree to revert this sign ?
