Calibrator caculation failed

I have model that from customer, I want to calibrate base on some SCADA signals of pressure which I was given. But I can't do that because it appear that "' 42513 "Base" "(N/A)" "-1" "(N/A)" 0.000 "An error occurred when trying to calibrate the model. Please check the model for errors." Calibrator Engine". Please help me how can I check this bug,

It sounds as if you received the model and used Darwin Calibrator.

Model calibration consists of two steps: 1. Determining the source of poor calibration and 2. making adjustments to make the model calibrated. Darwin is great for step 2. In my experience 95% of the work in calibration is in step one.

Before you think about using Calibrator, you need to make dozens of simulation runs with the different scenarios you will use to

1. make sure the models are stable,
2. identify which parameters the model is sensitive to,
3. look for inconsistent/inaccurate field data,
4. eliminate gross errors in the model due to incorrect connectivity and closed valves,
5. ensure that the elevations of the pressure sensors are correct and
6. generally get a feel for the model.

Only after you are sure that you have identified the source of model error should you try to make adjustments using Calibrator.

Best wishes in your work,

Thanks Dr.Tom Walski

I calibrated successfully, I export to scenario, alternative in order to run hydraulic. Unfortunately, It is so different HGL between Darwin results and hydraulic model results. How can I explain this issue?

This is where you as a hydraulic engineer need to review the model and data and determine WHY the model and the field data don't agree. This part is mostly detective work. There are many reasons why the model and field data don't agree. You need to go through them and eliminate possible reason until you determine the source of the problem.

If you're saying that you already calibrated the model and got good agreement between the model results and field data and are now trying to see the same results in the model itself that Calibrator provided, please take a look at the below Support Solution:

Hi Jesse Dringoli

I send to you a model that model from SAWACO utilities on sercue apload, When I try to Darwin Calibrator it always appear this bug "(N/A)"An error occurred when trying to calibrate the model. Please check the model for errors." We checked every aspects and it can run hydraulic caculation, but itsn't in Darwin Calibrator. Would you please let me know how I can fixed this bug?

Thanks and regards,
