PlantUnits Subpackage Structure

Main Goal Of this Subpackage

The main goals of this subpackage are:

• Getting the geometrical parameters and local parameters of each plant unit.

• Assigning the material and various models and properties of each plant unit to its parameters.

• Assigning the damage condition and data to related parameters during the analysis for post processing.

_GlobalParameters

In the following tables the existing global parameters and methods in _GlobalParameters.py of this subpackage has been shown:

Global parameters

Parameter	Description
V_unit	Parameter for total volume of the plant unit.
V_subs	Parameter for substance volume that has been stored in the plant unit.
Pressure	Parameter for internal pressure of the plant unit.
Temperature	Parameter for internal temprature of the plant unit.
Horizontal_localPosition	Parameter for local horizontal location of the plant unit.
Vertical_localPosition	Parameter for local vertical location of the plant unit.
FragilityTagNumbers	Parameter for the list of the fragilities tag of the plant unit.
SubstanceTag	Parameter for substance tag of the plant unit.
