Problem
When running a calibration study, the following error message occurs:
"Customer Meters associated with pipes are not currently supported with Darwin Calibrator or Designer."
In earlier versions, the following error would occur instead:
"An error occurred when trying to calculate or validate the model. Please check the model for errors"
Background
First, (and if the second "error occurred" message appears), check your Calibrator input for problems such as with formatting in the data for the calibration study. Carefully review the data to make sure it is correct and the formatting is correct. For instance, if you have a pump setting in the Boundary Override tab that is negative, this will cause an error message.
For the primary issue in question (and as the message suggests), currently customer meters associated with pipes are indeed not supported with Darwin Calibrator, for technical reasons. Development will review and potentially overcome this limitation in a future version (reference # 710678 and 727785).
Consider posting on our Idea Portal to help development prioritize.
Workaround
The workaround is to use the following steps to assign the customer meters to the nearest node element (junction, hydrant) in bulk:
1) Open Loadbuilder and create a new Loadbuilder run
2) Choose the option at the bottom of the first window to where it states "Customer Meter load data" and choose the Nearest Node method located on the right side of the window.
3) Choose the node layer as a selection set the users have if they only want to assign the meters to certain nodes or choose "Junction/All Elements".
4) Choose the Customer Meter Layer "Customer Meter/All Elements" and keep the check box unchecked for "exclude unconnected Customer Meters that already have a valid Associated Element".
5) Choose to update the existing alternative and select the alternative name. Add a Label to name the Loadbuilder run.
Note: you may need to review the results of this update to ensure that customer meter connections are acceptable.
