VCE_TNT Command

PhysicalEffect.VCE_TNT(tag, Etta=0.03)

This module is for modelling Vapor Cloud explosion with TNT model [Ref.1]. This model doesn’t work if no gas dispersion calculated in corresponding dispersion model in the previous step. So, the defined dispersion model should consider gas dispersion and if it models only liquid spread so no results will be back.

Argument	Type	Description
Tag	int	Unique integer value that will be used for referring to the defined elements or objects.
Etta	float	Explosion Yield Factor That is between 1% to 10% and it is recommended to be considered equal to 3%.

Example:

Create some imaginary materials:
