Output of the energy balance

Each of the energy quantities can be requested as output and can be plotted as time histories summed over the entire model, particular element sets, individual elements, or as energy density within each element. The variable names associated with the energy quantities summed over the entire model or element sets are as listed in Table 1.

Variable NameEnergy Quantity
ALLIE Internal energy, EI: ALLIE = ALLSE + ALLPD + ALLCD + ALLAE + ALLDMD + ALLDC + ALLFC.
ALLKE Kinetic energy, EKE.
ALLVD Viscous dissipated energy, EV.
ALLFD Frictional dissipated energy, EFD.
ALLCD Energy dissipated by viscoelasticity, ECD.
ALLWK Work of the external forces, EW.
ALLPW Work done by contact penalties, EPW.
ALLCW Work done by constraint penalties, ECW.
ALLMW Work done by propelling added mass (due to mass scaling), EMW.
ALLSE Elastic strain energy, EE.
ALLPD Inelastic dissipated energy, EP.
ALLAE Artificial strain energy, EA.
ALLIHE Internal heat energy, EIHE.
ALLHF External heat energy through external fluxes, EHF.
ALLDMD Energy dissipated by damage, EDMD.
ALLDC Energy dissipated by distortion control, EDC.
ALLFC Fluid cavity energy (negative of work done by fluid cavities), EFC.
ETOTAL Energy balance: ETOT=EI+EV+EFD+EKE+EIHE- EW-EPW-ECW-EMW-EHF.
In addition, Abaqus/Explicit can produce element-level energy output and energy density output, as listed in Table 2.
