Glossary
| IDA SE | IDA Simulation Environment, the simulation tool. Consists of IDA Modeler, IDA Solver and IDA NMF Translator. |
| IDA system | A full description of a simulation problem |
| Document | Either an IDA system or an auxiliary document: form, picture, plot file, text file |
| Model | A component of an IDA system or another model |
| Equation Model | A model described in a modeling language (NMF or Modelica) and compiled by IDA Translator. In IDA Modeler, the user has access to the parameters, variables and interfaces (links, connectors) in equation models, but cannot change the structure and equations of models. |
| Macro Model | A model that consists of connected models. Using IDA Modeler, the user can create macro models, change their structure and connections. |
| Data object | A common conception for the whole IDA system and any part of the system |
| Modeling | The process of building an IDA system |
| Simulation | The process of solving a simulation problem. IDA SE uses the IDA Solver. |
| Parameter | A property of the system that is not changed during the simulation. IDA SE supports several kinds of parameters: numerical, logical (Boolean), symbolical, strings, filenames, pointers to resources. The start values of variables are regarded as parameters. |
| Variable | A (potentially) time-dependent property of the system. IDA SE supports only numerical variables. |
| Interface | An ordered set of variables used for connections |
| Array | A collection of objects of the same type. IDA SE supports arrays of variables, parameters and interfaces. The size of array may be either constant or parameter(s). |
| Connection | The connection between two interfaces means that the corresponding variables are either equal or opposite (for flow variables with opposite directions). In some cases a direct connection between variables is possible. |
| Connection line | A line between two models in the schema that represents a connection between two interfaces of these models |
| Boundary | A connection with a constant or a given variable or interface. |
| Symbol | A graphical representation of a model in the schema. The inserting and deleting of the symbol means the inserting or deleting of the model. |
| Field | A graphical object that shows (and sometimes allows edit of) the value of some parameter in IDA system |
| Graphical element | An auxiliary graphical object used as illustration |
| Text element | An auxiliary graphical object containing text |
| Control element | A graphical object (usually a button or a hyperlink) that performs some action when activated |
| View | A view of an object is a window on the user’s display that show this object |
| View type | The method of showing a data object. The most common view types are form, editor, schema, outline, diagram and dialog. |
| To open an object | To open a view to the object |
| Simulation data | A set of parameters that describes how the system should be simulated, e.g., start- and end time. |
| Resource | Model used indirectly (by pointers or as templates). |
| NMF | Neutral Model Format, a modeling language |
| Modelica | An object-oriented modeling language designed by Modelica Association. |
| Shortcut menu (right-button menu, context menu) | The menu that pops up when the user click an object with right mouse button |
