SENERGY, OPT, ANTYPE
Determines the stored magnetic energy or co-energy.
OPTItem to be calculated:
0 | — | Stored magnetic energy. |
1 | — | Stored magnetic co-energy. |
ANTYPEAnalysis type:
0 | — | Static or transient. |
1 | — | Harmonic. |
SENERGY invokes an ANSYS 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 produced. 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 [ETABLE] and only retains the energy density or co-energy density. Use the PLETAB and PRETAB commands 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:
Orthotropic nonlinear permanent magnets.
Orthotropic nonlinear permeable materials.
Temperature dependent materials.
SENERGY is restricted to MKSA units.
