Notes

SENERGY invokes a Mechanical APDL macro which calculates the stored magnetic energy or co-energy for all selected elements. (For a harmonic analysis, the macro calculates a time-averaged (rms) stored energy.)

A summary table listing the energy by material number is generated. The energy density is also calculated and stored on a per-element basis in the element table (ETABLE) with the label MG_ENG (energy density) or MG_COENG (co-energy density). The macro erases all other items in the element table and retains only the energy density or co-energy density.

Issue PLETAB and PRETAB to plot and list the energy density.

The macro is valid for static and low-frequency magnetic field formulations.

The macro will not calculate stored energy and co-energy for the following cases:

SENERGY is restricted to MKSA units.
