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 (i.e. enthalpy change) if the stream components undergo complete combustion with oxygen to produce carbon dioxide gas and water. Available from Build 139. (Replaces old Heating Values option.) | |
| ValuesAtUserTandP | Additional variables will be evaluated at the user defined temperature and pressure | |
| SolutionImpurities | Impurity flows, fractions and concentrations. | |

| The following variables shows the species model that is used to calculate the physical properties of the contents, such as density, heat capacity, etc. | ||
| SpModel.Reqd | Inherit | Upstream configuration will be used. |
| 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'. | |

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. |

| Properties | ||

| Level / Lvl | Input / Display | This displays the level of the material contents. The user may also set the level in the unit here. |
| HiLevelLimit / HiLmt | Input | The highest allowable level of the unit. If the solids and liquids level rises above this value, the unit will give a warning. The default value is 102%, so if the user does not change this value, it will never give a warning. |
| LoLevelLimit / LoLmt | Input | The lowest allowable level of the unit. If the solids and liquids level drops below this value, the unit will give a warning. The default value is 0%, so if the user does not change this value, it will never give a warning. |
| LevelHi / LvlHi | Display | This is True (1) if the unit level is above the HiLevelLimit and False (0) otherwise. |
| LevelLo / LvlLo | Display | This is True (1) if the unit level is below the LoLevelLimit and False (0) otherwise. |
| LimitAsStatus | TickBox | If this is disabled then the warning messages for High and Low limits will not be displayed. |
