Comments

  1. Node path must be provided in the correct order through an unsortable node group identifier (/GRNOD/NODENS), which is mandatory.
  2. Detonation times are available in the Starter output file (IPRI ≥ 3).
  3. Burn fractions are available in the time history file with /TH/BRIC card and BFRAC keyword.
  4. Detonation velocity is taken from the /MAT/LAW5 (JWL).
  5. Only compatible with 2D modeling.
