9.3.1. User Interface

An Analytical Blast boundary condition can be defined and applied to parts in the same manner in which a stress boundary would be. The blast boundary condition parameters that need to be specified are as shown below.

The numerical inputs are as follows:

ParameterDescriptionNotes
Charge weight (kg)Weight of charge in equivalent weight of TNT (in kg)Must be greater than 0.
X-coordinate of blastX-coordinate of blast center in model units 
Y-coordinate of blastY-coordinate of blast center in model units 
Z-coordinate of blast (3D only)Z-coordinate of blast center in model units 
Blast start timeDetonation time in model time units 
Ambient Pressure (kPa)Ambient pressure in kPaMust be greater than or equal to 0.
Ambient Temp (K)Ambient temperature in KelvinMust be greater than or equal to 0.

Additionally, the following options can be specified:
