Infolytica结果里面energy和co-energy有什么区别啊？

这两个都代表什么意思？

Energy磁能，co-energy磁共能。Energy conservation, expressed in     terms of power, is established as Pinput = Ploss + Pmech + Pmag, where Pinput = VIPloss = POhm+ Piron (Piron      must be omitted unless a complex permeability is used) Pmech = F·v (linear      motion case) or T·w      (rotational motion case) Pmag = dEmag/dt(stored      magnetic energy Emag is      reported in the Post      processing bar) The power balance is demonstrated for the case of the Team Problem 30     MagNet modelReported stored magnetic energy might     be negative if permanent magnets are present [img][/img]Energy and co-energy are the same for a linear model
