Output for Global Variables
- IE: Global internal energy
- KE: Global kinetic energy
- TE: Total energy:
- TER: Rotational total energy:
- TTE: Translational total energy:
- DTE: Delta total energy:
- RKE: Global rotational kinetic energy
- CE: Global contact energy = CE_ELAST + CE_FRIC + CE_DAMP
- CE_ELAST: Elastic contact energy which is the recoverable energy stored in the contact penalty springs.
- CE_FRIC: Frictional contact energy.
- CE_DAMP: Damping contact energy. Only calculated for Interfaces TYPE2, 10, 18, 21, 23, and 25
- 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, Ishell = 1 – 4, and Ish3n = 1, 2 and solid elements Isolid = 1, 2. Numerical damping from Ishell = 12, 24 and Ish3n = 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.
