All /MAT/LAW5 (JWL) material law are affected by the detonation time.

(Integer)

  

Comments

  1. It is possible to define multiple detonation lines.
  2. If a detonation time is not defined, /MAT/LAW5 (JWL) material law will instantaneously detonate.
  3. Detonation times are available in the Starter output file (IPRI ≥ 3).
  4. Burn fractions are available in time history file with /TH/BRIC card and BFRAC keyword.
  5. Detonation velocity is taken from /MAT/LAW5 (JWL) material law.
  6. If A=B, then detonation wave is spherical.
  7. It is possible to manually set coordinates, instead of providing node_ID with /DFS/DETLINE/.
  8. node_ID1 and node_ID2 are mandatory.
