Working with models

A model consists of a number of Model Objects. A model object is typically a physical entity represented in the model, such as a reservoir, a river branch, a catchment, water user node etc. The types of available model objects depend on the type of model (simulation package). The model objects are organized in model object groups.

Example of a Model Object Groups:

Example of Model Objects within a Model Object Group:

To each model object is attached a number of variables, which describes the property of model object, e.g. reservoir characteristics for a reservoir. The variables may be a parameter (e.g. the initial water level in a reservoir) or a variable (e.g. time series water demand for a water user node object).

The model object variables describe the properties of a model object. For a model created with MIKE BASIN, the model object representing a water user node will include the following variables, which includes both input data variables and output data variables (results).

Example of Model Variables of a model object:

The model set up, the model objects and the variables are presented in a data view section. The data view section consists of a map section in which the model topology is displayed (top), and an explorer section, where the model objects and variables are presented (bottom).

The explorer can be used to drill down into the model hierarchy from model object to the variable information. The location in the hierarchy is illustrated by a bread crumb control on the top of the explorer.

View basic model properties

Click on the model in the explorer to view the general properties of a model.

The properties are now displayed in the Properties control.

The properties include information about:

  • Description (editable)
  • Model Name (editable)
  • Model tool
  • Simulation period

View model properties in the data view

Double click or right click and select Open from the context menu to view the model properties.

Note

Note: In the following the data view for models is called the model view.

In the map section is now shown the schematization of the model.

In the Explorer section is now shown the model objects group

Double-click on a Model Object Group to view a list of all model objects of a given type (The name of the group indicates the type of model objects contained in the group).

Double-click on a Model Object to view a list of all model object variables.

Note: The bread crumb control which shows the current location in the hierarchy is in the Water user node group.

To move back to the root of the explorer, click on a higher link in the bread crumb control.

To view a model object variable, double-click one of the model objects in the list. The characteristics of the variable is shown in a Chart View.

Model object variables, e.g. an input variable, can be analyzed using one of the tools displayed in the Tool Explorer.

Browse to the model object variable level.

Select one or more input variables.

Notice the tool explorer now gets populated with the tools that apply to the selected model object variable type (e.g. a time series).
