SI Unit Example

detcord_ID

Detonator identifier

(Integer, maximum 10 digits)

 

VDET

Detonation velocity

Default= 0.0 (Real)

= 0.0: means instantaneous detonation

TDET

Detonation time

Default = 0.0 (Real)

Iopt

Option flag

(Integer)

= 0: Instantaneous detonation

= 1: Use Detonation velocity parameter

 

mat_ID

Explosive material number concerned by detonation time.

(Integer)

= 0: all JWL material law are affected by the detonation time.

 

grnod_ID

Mandatory node group identifier defining the cord.

(Integer)

 
hmtoggle_plus1Comments
1.It is possible to define multiple detonators.
2.If a detonation time is not defined, JWL material law will instantaneously detonate.
3.Detonation times are available in the Starter listing 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 JWL material law. Cord detonation is instantaneous.
6.Defining only two nodes leads to a detonating line /DFS/DETLINE.
