Create a flowsheet parameter or a flowsheet variable

Create a flowsheet parameter from the Simulation Manager

1. In the Simulation Manager, right-click the Main branch, and then in the Add Parameter submenu, select the parameter type that you want to use for the flowsheet parameter.

   The new flowsheet parameter appears in the Simulation Manager, under the Main branch.

   The new flowsheet parameter uses:

   • A default name.

   • The default value for the parameter type that you used to create the flowsheet parameter.

   • The default unit of measure (UOM) for the parameter type that you used to create the flowsheet parameter.

2. (Optional) Rename the flowsheet parameter. See Rename a flowsheet parameter or a flowsheet variable for more information.

3. (Optional) Select the default value for the flowsheet parameter, and then enter a new value.

4. (Optional) Select the default UOM for the flowsheet parameter, and then in the resulting list of UOMs, select the UOM that you want to use for the flowsheet parameter.

Create a flowsheet parameter from the Tools Library

5. Drag a Parameter from the Tools Library onto the Canvas.

   A new flowsheet parameter appears in the Simulation Manager, a Variable Reference for the flowsheet parameter appears on the Canvas, and the properties dialog for the flowsheet parameter opens.

   Tip: If you inadvertently close the properties dialog, you can reopen it by right-clicking the Variable Reference on the Canvas or the flowsheet variable in the Simulation Manager and then selecting Parameter Properties.

6. In the properties dialog for the flowsheet parameter, in the Name box, enter the name that you want to use for the new flowsheet parameter.

   The Variable Reference name updates to match the flowsheet parameter name.

7. Select the dropdown arrow for the Type list, and then select the desired parameter type.

   The value and UOM for the flowsheet parameter update to match the default value and UOM for the selected parameter type.

   The Variable Reference value and UOM also update to match the default value and UOM for the selected parameter type. However, you can change the Variable Reference UOM independently of the UOM for the flowsheet parameter. Also, deleting the Variable Reference does not affect the flowsheet parameter.

8. Do one of the following to close the properties dialog:

   • Select x on the dialog.

   • Select anywhere on the user interface outside of the dialog.

9. (Optional) Do one of the following to update the value for the flowsheet parameter:

   • In the Simulation Manager, locate the flowsheet parameter, select its value, and then enter the new value.

   • On a Variable Reference for the flowsheet parameter, select the value, and then enter the new value.

10. (Optional) Change the UOM for the flowsheet parameter by doing the following:

    1. In the Simulation Manager, locate the flowsheet parameter.

    2. Select the UOM for the flowsheet parameter.

       A list of available UOMs appears.

    3. In the list of UOMs, select the UOM that you want to use for the flowsheet parameter.

    Integer parameters do not include a UOM.
