*CONWEP CHARGE PROPERTY

Define a CONWEP charge for incident waves.

This option defines parameters that create the time history of pressure loading used to simulate an explosion in air. This option must be used in conjunction with the INCIDENT WAVE INTERACTION PROPERTY option. The pressure loading is calculated using the CONWEP model empirical data in which mass, length, time, and pressure are given in specific units. Multiplication factors are defined for conversion between the CONWEP data units and the analysis units.

Data lines to define the CONWEP charge properties

First line

  1. Equivalent mass of TNT in any preferred mass unit.

  2. Multiplication factor to convert from the preferred mass unit to kilograms. The default is 1.0.

Second line (enter a blank line if the analysis uses SI units)

  1. Multiplication factor to convert from the analysis length unit to meter.

  2. Multiplication factor to convert from the analysis time unit to second.

  3. Multiplication factor to convert from the analysis pressure unit to pascal (N/m2).
