COCO - CAPE-OPEN to CAPE-OPEN simulation environment

Inserting objects

From the Insert menu, various types of objects can be inserted into the flowsheet:

Moving, sizing and deleting objects

To move an object, drag the object to the desired location. To size an object, drag one of the size handles of the object to obtain the desired size. To delete an existing object, select the object and hit Delete.

An object can be selected by clicking on it. Multiple objects can be selected by drawing a marquee around it. Individual objects can be added to the selection or removed from the selection by holding down Shift or Control while selecting the object.

You can change the properties of an object by double-clicking on the object.

A selection of multiple objects can be moved or deleted at the same time. Scaling for multiple objects is not supported.

Stacking order

The order in which the objects are drawn is called the stacking order. This determines which object is in front in case of overlapping objects. You can change an object's location in the stacking order by clicking on the object with the right mouse button and select Move Up, Move Down, Move To Top or Move To Bottom.


Reports behave like any other object, except for the size of a report is determined by its content. You can change the font size (and therefore the report size) and some other properties that affect the size of the report from the Format page by double-clicking on the report.

Reports will automatically be updated as the data in the report changes. The unit of measure of the data is the same unit of measure that is used for the data in other contexts. For stream properties, the unit of measure can be modified from the stream display (double click on a stream), or from the Properties page of the Flowsheet Configuration.

The unit of measure by default shows as a separate column at the end of the table. This can be turned off in the report configuration; the unit of measure will then show in the property column.

Stream reports

Stream reports will show selected properties of selected streams. Double click the report to select streams, and change the order of streams. Overall properties as well as per-phase properties can be selected. For energy and information streams, the selected properties are ignored, and all data contained in the stream is shown.

Overall properties as well as properties for each existing phase can be added to the report. On the Format configuration tab, the composition threshold will cause compounds for which the composition fraction is below this number show as zero composition or zero component flow.

Unit reports

Unit operations optionally come with reporting functionality. One can check the reports that are exposed by a unit operation by double clicking on the unit operation and inspect the first tab. The "Solve log" report if present is generated by COFE, and not part by the unit operation.

Upon inserting a unit report in the flowsheet, the unit operation and the desired report must be selected. Additional report properties, like tab size and line wrapping, can be specified.

Unit parameter reports

Unit parameter reports will show values for parameters of unit operations. You can add multiple parameters of multiple unit operations to the same report.

Author report

The author report will show the following properties (if filled in): title, author, company and document creation date. These can be modified by selecting Properties from the File menu.
