Use Workspaces

Open a workspace🔗

  1. Open Modelon Impact

  2. Select workspace to open from Recent or All

  3. Click on the workspace that is to be opened. The lock icon indicates that the workspace is locked by a user.

  4. A specific workspace can be opened directly in the browser using URL: e.g. http://127.0.0.1:8080/workspaces/workspace_name.

  5. Other options: New workspace. Import a workspace.

Unlock a workspace🔗

  1. Click on the home symbol (Modelon Impact logo in the upper-left corner) to close the current model.

  2. Click on the home symbol again to unlock the current workspace and navigate to the Welcome page.

  3. The workspace lock icon will disappear.

Create a workspace🔗

The workspace is where a user stores models and experiments. A library resource must be copied to a workspace in order for it to be edited. Once a workspace name is set, it cannot be changed. To change name, create a new workspace. Workspace folders can be renamed.

  1. Open Modelon Impact
  2. Click on icon found at the bottom of the start page.
  3. Add a new workspace name.

Switch workspaces🔗

Most users will have various workspaces. It is possible to switch between them.

  1. Click on the home symbol (Modelon Impact logo in the upper-left corner) to close the current model.
  2. Click on the home symbol again to release the current workspace and navigate to the Welcome page.
  3. Browse and select an existing workspaces or create a new one.

Reorganise models🔗

  1. Models (and sub packages) can be dragged between Workspace (packages) inside the Workspace package to reorganize them.

  2. References are automatically updated when a class is moved to a new allocation.

  3. It is possible to drag a class to a specific location within a package.

  4. Dropping an item on a package will put it last in the package.

  5. There is an indication showing where the class will be dropped.

Enable/Disable a Global Library in a workspace🔗

By default, all available Global Libraries are enabled and accessible in the Library Browser of a new workspace.

  1. Click the button on the right.
  2. Uncheck the checkboxes for the libraries you don't want to load; Impact will remember this configuration the next time the workspace is opened.
  3. The Modelica Standard Library (MSL) cannot be disabled.

Find model🔗

Starting with an example, template or existing model is an efficient way to build a model with the right fidelity needed for your tasks. Global Libraries include predefined examples and templates, see, for example, Modelica.Blocks.Examples.PID_Controller.

  1. Example models are typically stored in a folder named Examples or Experiments or Templates.

  2. To find such models, browse through the library of interest and look for such folders. Alternatively, utilize the filter functionality in the Library Browser to identify Examples, Experiments or Templates*.

  3. A single mouse click is sufficient for expanding the tree-structure and browsing through the libraries, but a double-click is required to open a model.

  4. Since Global Libraries are read-only, the example models need to be duplicated to edit them. To edit an example, right-click on it in the Library Browser, select Duplicate to..., and choose the workspace package you wish to duplicate the example model to. The model will then be free to be edited from your workspace.
