Using Injectors
An injector has a type, which determines how it generates injection points. Particles are introduced at these injection points and are assigned to the user-specified Lagrangian phase.
Injector nodes represent injectors within the injector manager. They are created using the right-click menu on the injectors manager node. The injector node has its own properties. It contains condition and value objects that apply to the Lagrangian phase to which it is assigned.

The goal of an injector is to provide the initial state of particles, according to its user-specified conditions and values. The injector type and the models of the Lagrangian phases determine these conditions and values.
Injector Properties
- Index
- A unique identifier for this injector (read-only)
- Lagrangian Phase
- Selects the Lagrangian Phases from a dialog box. Deselecting all phases deactivates the injector.
- Type
- The injector type. The possible types are listed below.
- Film Stripping
- A film stripping injector.
- Volume Stripping
- A volume stripping injector.
- Lattice Injector
- A lattice injector.
- Part Injector
- A part injector.
- Point Injector
- A point injector.
- Hollow Cone Injector
- A hollow cone injector.
- Solid Cone Injector
- A solid cone injector.
- Random Injector
- A random injector.
- Surface Injector
- A surface injector.
- Nozzle Injector
- A nozzle injector.
- Parcel Transfer
- A parcel transfer injector.
- Table Injector
- A table injector.
- Inputs
- Selects the parts that are used to generate the injection points. How the parts are used and which parts can be selected depend on the injector type.
- Number of Points
- The number of injection points this injector produces (read-only). The injection points are first generated when the solution is initialized.
- Retain Injected Parcels
- When On, data from an injector is available for post-processing, including by extracting injection data into XYZ internal tables. The default is Off.
To set up an injector, do the following:
- Create the injector
- Assign a Lagrangian phase
- Set the injector type
- Assign the injector parts
- Set conditions and values
Other operations that can be performed on an injector node are:
Creating an Injector
To create an injector, right-click the Injectors manager node and select New.

Assigning a Lagrangian Phase to the Injector
To assign a Lagrangian Phases to an injector, select the injector node and select that phase from the dialog box of the Lagrangian Phase property. The dialog box uses dynamic queries, so you can select phases by attached tags.

Setting the Injector Type
To set the injector type, select the injector node and select the required type from the drop-down list of the Type property.

Assigning the Injector Parts
To assign the input parts of the injector, click the right half of the Inputs property of the injector node. This action activates the Inputs dialog, which uses dynamic queries.

The displayed selection contains parts appropriate to the injector type; not all parts are appropriate for every injector.
Setting Conditions and Values
Each injector contains sub-nodes that are managers of injector conditions and values, which work in ways similar to the conditions and values for a Simcenter STAR-CCM+ simulation.

Renaming an Injector
Similar to other objects, an injector can be renamed within Simcenter STAR-CCM+.
Deleting an Injector
Injectors can be deleted from an existing simulation.
Injector Manager Pop-Up Menu
This pop-up menu item is available when you right-click the Injectors manager node.
