Output for Global Variables

IE: Global internal energy
KE: Global kinetic energy
TE: Total energy: $T E = I E + K E$
TER: Rotational total energy: $T E R = I E + K E + R K E$
TTE: Translational total energy: $T T E = I E + K E + R K E + C E + H E$
DTE: Delta total energy: $D T E = T T E - E F W$
$D T E_R E L = \frac{T T E - E F W}{T T E}$

HE: Global hourglass energy 5
EFW: Global external work
XMOM: Global momentum in X direction in global reference frame
YMOM: Global momentum in Y direction in global reference frame
ZMOM: Global momentum in Z direction in global reference frame
MASS: Global mass of the structure, including lumped mass and mass added due to mass scaling from using /DT/NODA/CST
DT: Time step
SIE: Global spring internal energy
VX: X velocity
VY: Y velocity
VZ: Z velocity

Comments

Global variables are always written and do not need to be requested.
Variable names must be left justified.
In 2D axisymmetrical computation, energies are given per radian.
Global internal energy includes all material internal energy and global spring internal energy, but not spring rotational internal energy.
Global hourglass energy output only includes perturbation hourglass energy for shell elements, I_shell = 1 – 4, and I_sh3n = 1, 2 and solid elements I_solid = 1, 2. Numerical damping from I_shell = 12, 24 and I_sh3n = 30, 31, is not included in global hourglass energy but can be output /TH/PART, hourglass energy output.
Additional time history files (Runname_run#_i.thy) with different frequencies and variables can be generated through the option /iTH (where i = A to I). These options use the same keyword format and variables as option /TH, except for the addition of the prefix (/ATH, /BTH ...). The frequency at which data is written to these additional files is defined in the Radioss Engine option /ATFILE.
