Problem Description

After creating a custom quadrant curve for pumps or turbines in HAMMER in the QuadrantCurves.txt file, the specific speed is not displayed or available for selection in the element properties.

Steps to Resolve

First, make sure the formatting for the custom quadrant curve is correct. For more information on creating quadrant curves, please refer to the HAMMER Help topic "Pump and Turbine Characteristics in Bentley HAMMER".

If the formatting and setup are correct, the issue may be related to the exact version you are using. When HAMMER is installed on a 64-bit machine, both the 32-bit and 64-bit versions of the program are included. The QuadrantCurve.txt file you need to edit will depend on the version of the program that you are using. You can find out what version you are using by going to Help > About HAMMER. If you are using the 64-bit version, this will be displayed in the lower left near the build number.

If you are using the 64-bit version of HAMMER, you will need to edit the text file found at C:\Program Files (x86)\Bentley\HAMMER8\x64\QuadrantCurve.txt. When you do this, the specific speed will be listed. If you edit the 32-bit version of the quadrant curve text file (found at C:\Program Files (x86)\Bentley\HAMMER8), the specific speed will not be listed.
