Cause:

The output parameter has been specified multiple times (in different components)

Action:

Since version 11 it is not allowed/not recommended to specify certain parameters multiple times. A temperature can be set by a components exit station, or by the next component inlet station temperature option. GSP will automatically check and repair old models where options are defined multiple times for most options. An exception are the shaft speed options, these are not automatically updated and have to be done manually.

There is a simple solution to solve this. Actually this is a warning, and not an error, so the calculation will continue if you press the ignore button.

There are 2 ways to solve this warning from popping up:

1)Individual output tab sheet setting (the following describes the setting of the output options for shaft speed, but can be applied to other output parameters)
Check the Output tab sheet of every component that is connected to the same shaft and be sure only one of these components has the Shaft options (check boxes) N [rpm] and N [%] checked:
a - Open your model
b - Double click first component connected to the first shaft
c - Go to the Output tab sheet
d - Put a check mark in N [rpm] and N [%] options and close the component input window with OK
e - Double click next component connected to the shaft
f - Go to the Output tab sheet
g - Clear the check mark in N [rpm] and N [%] options and close the component input window with OK
h - Proceed to step e until all components for that shaft have been set
i - If applicable, double click first component connected to the next shaft and proceed to step c

2)Central output parameter setting: (preferred solution)

1 - Open your model

2 - Go to the menu item Options then select Output...

3 - Go to the Components tab sheet on the Output Parameters tab sheet

4 - Set the drop down selection box at the bottom to All Turbo Components

5 - Put a check mark in N [rpm] and N [%] options (if these are already checked please uncheck and check again to activate the Apply Changes button)

6 - Press the Apply Changes button (this will automatically set the correct settings per shaft)

7 - Close the output options window with OK
