Block Format Keyword Describes a planar detonation wave.
is the direction of propagation. Detonation velocity
(D) is taken from JWL material law.
Lighting time is set to TDET on the
plane normal to containing basis point P.Figure 1.

Comments
Detonation time is
TDET in plane containing basis
point P.
It is possible to
define multiple detonators with different types and lighting times.
If a detonation option is not
defined, all JWL material law will instantaneously detonate.
Burn fractions are available in
time history file with /TH/BRIC card
and BFRAC keyword.
Detonation times can be written in
the Starter output file for each JWL elements. Printout flag
IPRI ≥ 3 (/IOFLAG).
