Comments

  1. Global variables are always written and do not need to be requested.
  2. Variable names must be left justified.
  3. In 2D axisymmetrical computation, energies are given per radian.
  4. Global internal energy includes all material internal energy and global spring internal energy, but not spring rotational internal energy.
  5. 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.
  6. 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.
