Introduction

This section is used to display material content and all the associated properties. For example there will be a Content and M section in a Tank - Dynamic Mode.

This model primarily has read only variables, and a few options that affect how information (or views) are displayed. The species model that is used will affect the display and may result in some extra fields or tab pages. The default 'Standard' species model will be described here.

Content Tab Page

Tag (Long/Short)	Input / Calc	Description/Calculated Variables / Options
Displays a list of properties that the user can view or hide by clicking on the required property.
	Energy	Fields related to Thermodynamic properties, e.g. Hz, Hs, Cp, etc.
	Saturation	Fields related to the properties of the default Saturation species (usually H2O).
	pH_Estimate	Fields related to the pH estimate
	Charge	Fields related to Charge
	Transport	Transport properties such as viscosity and thermal conductivity
	DensityCorrections	Additional density correction variables
	HeatsOfCombustion	The Heat of Combustion is the heat released (ie. enthalpy change) if the stream components undergo complete combustion with oxygen to produce carbon dioxide gas and water. Only available in Build 139 or later (replaces old Heating Values option).
	ValuesAtUserTandP	Additional variables will be evaluated at the user defined temperature and pressure
	SolutionImpurities	Impurity flows, fractions and concentrations.
	H2OProperties	Properties of pure water and steam

The following variables shows the species model that is used to calculate the physical properties of the contents, such as density, heat capacity, etc.

	Standard	All the variables are calculated using the Mass Weighted Mean of the species.
	Species Model	Use an alternative species model, such as 'Bayer3' or 'Potash'.
SpModel.Used	Standard	The Standard species model is being used.
	Species Model	An alternative species model is being used.
SpModelType	Display	This field displays the Species Model type (or Name) used.
SpMdlIdNo	Display	This field displays a unique number generated when the Species Model is created.
ShowHeatingValues	Tickbox	Only available in Build 138 or earlier. If ticked, then the calorific Heating Values of the material in the content will be displayed. For Build 139 or later, refer to Heats Of Combustion.
Qualities
Lockup.Action	Input / Display	The user may select Modify Content. The 'Lockup' values are set on the 'DLockup' tab. The field displays the actual state of the Lock Up function: If this has been enabled then this will display 'Lockup.Action(On)', otherwise it will display 'Lockup.Action'. Please see LockUp for more information. Note: Lockup must first be enabled on the Plant Model - Qualities Tab and created upstream of the surge unit before the user may modify it here.
MatTrack.Action	Input / Display	The user may select Modify Content. The 'Tracking' values are set on the 'DTrack' tab. The field displays the actual state of the Material Tracking function: If this has been enabled then this will display 'MatTrack.Action(On)', otherwise it will display 'MatTrack.Action'. Please see Material Tracking for more information. Note: Material Tracking must first be configured on the Plant Model - Qualities Tab and created upstream of the surge unit before the user may modify it here.
SzDist.Action	Input / Display	The user may select Modify Content. The 'Size Distribution' values are set on the 'DSz' tab. The field displays the actual state of the Size Distribution function: If this has been enabled then this will display 'SzDist.Action(On)', otherwise it will display 'SzDist.Action'. Please see Size Distribution (PSD) for more information. Note: Size Distribution must first be created upstream of the surge unit before the user may modify it here.
SzSSA.Action	Input / Display	The user may select Modify Content. The 'SSA' values are set on the 'SSA' tab. The field displays the actual state of the SSA function: If this has been enabled then this will display 'SzSSA.Action(On)', otherwise it will display 'SzSSA.Action'. Please see Specific Surface Area (SSA) for more information. Note: SSA must first be created upstream of the surge unit before the user may modify it here.
Lockup.InUse	Display	Displays the state of the LockUp function: Yes or No.
MatTrack.InUse	Display	Displays the state of the Material Tracking function: Yes or No.
SzDist.InUse	Display	Displays the state of the Size Distribution (PSD) function: Yes or No.
SzSSA.InUse	Display	Displays the state of the Specific Surface Area (SSA) function: Yes or No.
Properties
This section is shown in the Dynamic Tank model but not in the Multi-Storage model.
Temperature / T	Input / Display	This displays the temperature of the material contents. The user may also change the temperature here.
