Activating a Configuration Set :: Running Simulations (Using Simulink)

Using Simulink

Activating a Configuration Set

To activate a configuration set, right-click the configuration set's node to display the node's context menu, then select Activate from the context menu.

Copying, Deleting, and Moving Configuration Sets

You can use edit commands on the Model Explorer's Edit or context menus or object drag-and-drop operations to delete, copy, or move configuration sets among models displayed in the Model Explorer's Model Hierarchy pane.

For example, to copy a configuration set, using edit commands:

Select the configuration set that you want to copy in the Model Hierarchy pane.
Select Copy from the Model Explorer's Edit menu or the configuration set's context menu or press Ctrl+C.
Select the model in which you want to create the copy

Note You can create a copy in the same model as the original.

Select Paste from the Model Explorer's Edit menu or from the model's context menu or press Ctrl+V.

To copy the configuration set, using object drag-and-drop, hold the Ctrl key and the right mouse button down and drag the configuration set's node to the node of the model in which you want to create the copy. To move a configuration set from one model to another, using drag-and-drop, hold the Ctrl key and the left mouse button down and drag the configuration set's node to the node of the destination model.

Note You cannot move or delete a model's active configuration set.

Copying Configuration Set Components

To copy a configuration set component from one configuration set to another:

Select the component in the Model Explorer's Contents pane.
Select Copy from the Model Explorer's Edit menu or the component's context menu or press Ctrl+C.
Select the configuration set into which you want to copy the component.
Select Paste from the Model Explorer's Edit menu or the component's context menu or press Ctrl+C.

Note The copy replaces the component of the same name in the destination configuration set. For example, if you copy the Solver component of configuration set A and paste it into configuration set B, the copy replaces B's existing Solver component.

Creating Configuration Sets

To create a new configuration set, copy an existing configuration set.

Setting Values in Configuration Sets

To set the value of a parameter in a configuration set, select the configuration set in the Model Explorer and then edit the value of the parameter on the corresponding dialog in the Model Explorer's dialog view.

Configuration Set API

Simulink provides an application program interface (API) that permits you to create and manipulate configuration sets from the command line or in a MAT-file or M-file. The API includes the Simulink.ConfigSet data object class and the following model construction commands:

These commands, along with the methods and properties of Simulink.ConfigSet class, allows an M-file program to create and modify configuration sets, attach configuration sets to a model, and set a model's active configuration set. For example, to create a configuration set from scratch at the command line, enter

```
cfg_set = Simulink.ConfigSet
```

The default name of the new configuration set is Configuration. To change the name, execute

```
cfg_set.Name = 'name'
```

where name is the set's new name.

Use get_param and set_param to get and set the value of a parameter in a configuration set. For example, to specify the Simulink fixed-step discrete solver in the configuration set, execute

set_param(cfg_set, 'Solver', 'FixedStepDiscrete')

To save the configuration set in a MAT-file, execute

```
save mat_file cfg_set
```

where mat_file is the name of the MAT-file. To load the configuration set, execute

```
load mat_file
```

To prevent or allow a user to change the value of a parameter in a configuration set, execute

setPropEnabled(cfg_set, 'param', [0 | 1])

where param is the name of the parameter. To attach a configuration set to a model, execute

```
attachConfigSet(model, cfg_set)
```

where model is the model name (in quotes) or object. To get a model's active configuration set, execute

```
cfg_set = getActiveConfigSet(model)
```

To get a configuration set's full name (e.g., engine/Configuration), execute

```
getFullName(cfg_set)
```

To set a model's active set, execute

```
setActiveConfigSet(model, cfg_set)
```

where cfg_set is the configuration set's name in quotes.
