# Application Layout

The application work screen consists of two main windows. The flowsheet window where a schematic layout of the piping network is developed or built, and the data palette where data input is made, and results and warnings are shown. You can have as many flowsheets open as desired. From a flowsheet viewpoint the application behaves similar to Microsoft Word's Multiple Document Interface, that is, you can tile, cascade, and select a flowsheet from the window menu or by clicking on the caption bar of the window. If you double-click the caption bar the flowsheet fills the available work area. The data palette size can be adjusted by dragging the left side of the window border. The data palette is synchronized to the flowsheet, so if you click on a flowsheet element, the data palette is refreshed to reflect the current selections(s). This process also works in reverse, for example, if you click an element warning in the data palette, or a list item, the flowsheet selection updates to reflect this. All palettes can be undocked by either dragging via the caption bar or by double clicking on the caption bar. The data palette has 6 tabbed windows used to display:
1. | Messages and hints as a list with more detailed explanations available.
2. | Input data via an Input Inspector, the rows in the input inspector vary depending on the element selected.
3. | Result data via a configurable table.
4. | A chart showing equipment performance data graphically.
5. A list of all flowsheet elements. You can decide which elements to display and the list can be sorted.
6. | A watch window that is active only during a calculation.
The screenshot below shows the main parts of the application, with two open flowsheets and the data palette tabbed to show the input tab. The input tab contains the Input Editor. At the top of the work screen are three rows of operators: (1) a set of drop down menus; (2) a toolbar; (3) the component palette. The component palette consists of a series of tab options. Within each tab are the equipment item icons or elements that are used to build a fluid network. A flowsheet toolbar is positioned along the left hand side of the screen. Options here determine how you access and utilize the flowsheet window. A status bar is positioned at the bottom of the application. This provides a quick reference to flowsheet status and to calculation methods used. The number of panels in the status bar depends on the modules you have activated, so the status bar in your installation may have fewer panels than shown above.
