The user interface of MERLIN-Expo is organised as ten screens which are accessed through tabs (coloured blue in the picture above). The tabs are ordered as the screens are intended to be used:
Each screen features a row of buttons referred to as the tool bar (coloured red in the picture). These buttons give you access to functionality such as saving a project, exporting/importing values or changing simulation settings.
Some screens display a list of items on the left hand side (coloured yellow in the picture). When you select an item, information about the item appears in the panel on the right (coloured cyan in the picture).
Under the list are a set of controls (coloured green in the picture) that allow you to search for specific items:
Name - Enter part of or the whole name of an object to hide all other objects. Category - Select the category of the object. Tags - Select one or more tags for the object. Only objects with all the selected tags will be shown. Sub-system - Select the sub-system (sub-system) of the object. -Selected sub-system- will show objects for the currently selected sub-system in the model screen.
Some screens feature a button named Information. When you clicked, a browser like panel is displayed in which information about the currently selected object(s) is presented. This includes general information, such as the name and dimension of the object, information on which other objects are using the objects as well as all the equations, or values, of the object. Click the links in the browser to find out more about other objects.
