General Description
By enabling a Makeup (MU) Block within a unit, the user may add flow to the unit in a controlled fashion. There are a number of advantages to using a MU block to add material to a unit:
- The user needs to add and configure only a single Makeup Source to feed many different units in a project.
- Since the Source is not connected to the MU with a standard link, there is no need for multiple links to be constructed.
- The user may often be able to avoid using either a PID or General Controller to control the addition.
- The MU ensures that the unit always has the correct flow at each iteration, or step, and hence this prevents 'lags' that can be a problem with controlled flows in Dynamic projects.
- A MU is a useful trick to setting up flow in a recirculating loop. Setting flow in a loop
The Makeup Block (MU) can be added to a number of models, such as the Tie, Tank, Feeder-Cross Page Connector, Pipe and many Mass Separation models.
Notes:
- The MU block gets the flow from the Makeup Source, so this unit must be inserted before enabling the MU in a unit.

The following videos are part of the Tutorial showing users how to insert and configure a Makeup Block:
Adding Makeup to a Unit
Step 1 - Enable Makeup
The Makeup Block is enabled in a unit when the user enters an integer between 1 and 8 for the number of Makeups in the unit's access window.
The user may enable more than one Makeup Block per unit, by entering 2, 3, etc. The unit will then have the appropriate number of Tabs: MU1, MU2, MU3, etc. The user must then configure the Makeup Block(s) by clicking on the MUX tab.
Notes:
- The Makeup Block is a sub-model which is evaluated sequentially. The user can change the order that the sub-models are solved using the drop down lists on the first tab page - Off, On-AutoSequence, On-Sequence1, On-Sequence2, etc.
- The AutoSequence option will evaluate the sub-models as follows:
- 1st - Makeup;
- 2nd - Reactions;
- 3rd - Environmental Heat eXchange; and
- 4th - VLEquilibrium.
- For example, a Makeup may be added either before or after a reaction block sub-model.
- If the Makeup is a reactant then it must be added prior to the reaction block.
- If the user wants to achieve a final concentration from the unit then the Makeup block should be the last sub-model.
- Due to the sequential nature of the sub-models, Makeups can not be used to achieve a final concentration of a reactant.
Step 2 - Connect to a Makeup Source
The next step is to connect the Makeup Block to a Makeup Source. Go to the MU tab and select the Makeup Source from a drop down list of available Makeup sources in the project.
Once a valid Makeup Source has been entered into the MakeupSrc field, a graphics symbol for the DirectLink will be displayed indicating that the unit has additional input. (Note: The user may change the name of this DirectLink or its graphical symbol in exactly the same way as for any other unit in SysCAD).
Step 3 - Configure the Makeup Block
The Makeup Block may then be configured as:
- None
- Fixed Makeup
- Ratio Makeup
- Product Flow
- Product Composition
- Product Mass Concentration @T
- Product Mass Concentration @25°C
- Product Molar Concentration @T
- Product Molar Concentration @25°C
- Product Density
- Product pH Estimate
- Product User Calculation
- Product Species Calculation
- Product Species Model Property
- Product Temperature
- Temperature Change
Each of the different options that can be configured are described in the table below.
NOTE:
- When setting up the makeup block, it’s crucial to understand the evaluation order of the MU block. The term “Feed” refers to the material entering the MU block. This means that if the MU block in question is the second evaluation block in the sequence, then the “Feed” for this MU block would be the “Product” from the first evaluation block. Similarly, the term “Product” (as used in the method Product Flow) refers to the material exiting the MU block. It’s important to note that this may not be the same as the Discharge product from the process unit if other evaluation blocks are used after the MU block.
Data Section
The default access window (MU) and variable names are described in detail in the following tables. These variables change as the user selects the various options that are available. Individual tables are shown for each Makeup Model, except for the Common Requirements and Common Results tables that show fields that are common to all methods.

Fixed Makeup Model
| Tag (Long/Short) | Input/Calc | Description |
|---|---|---|
| Reqd.Basis | MassFlow | The user specifies the Makeup amount as a mass flowrate. |
| VolumeFlow | The user specifies the Makeup amount as a volumetric flowrate at temperature. | |
| VolumeFlow25 | The user specifies the Makeup amount as a volumetric flowrate at 25°C. | |
| NVolumeFlow | The user specifies the Makeup amount as a volumetric flowrate at Normal Temperature. | |
| MoleFlow | The user specifies the Makeup amount as a molar flowrate. | |
| MakeUp Measurement | ||
| Selection | All | The amount of material added is based on the Total makeup stream. |
| Phase | The user can select the different phases to be included in the specified amount. For example, if the make up source has 50% solids and 50% liquids, and the user wants to specify a mass flow of 10t/h of solids, then only leave the solids tick box checked and SysCAD will add to the MUx block enough makeup to give 10t/h solids. In this case, a total of 20t/h will be added. | |
| IndividualPhase | As per Phase, the user is allowed to select the individual phase to be included in the specified amount. For example, if user wants to specify the organic addition - individual phase (or) to be 10t/h then select the (or) individual phase, and the makeup block will add enough to give 10t/h organic.
Note: To do so, user must have defined (or) phase in the species database and the makeup source must contain organics as part of its composition. | |
| All Species/Species | The user may select individual species to be included in the specified amount.
| |
| Solid Species | Only available in Build 138 or later. The user may select individual solid species to be included in the specified amount. Up to 20 solid species can be selected. | |

| Vapour Species | Only available in Build 138 or later. The user may select individual vapour species to be included in the specified amount. Up to 20 vapour species can be selected. | |
| Component | As per species above. The difference between species and component is that species is phase based, while a component is phase independent. For example, if NaCl is defined in the (aq) and (s) phases, and user wishes to select the solid phase only, then use the Species option and choose NaCl(s). If user wants to include both phases, then use the Component option and choose NaCl. | |
| Element | The user may select individual elements to be included in the specified amount. | |
