FACING ISSUE IN RUNNING SIMULATIONS. NEED HELP IN FINDING THE CAUSE

I am attaching the image below which shows error i am facing while doing simulations of parabolic trough system. Can you help me finding the root cause and guide over that ?

Thanks

Dear Muhammad,

I could not read the text in the photograph. A screenshot would be easier to read.

If you are new to SAM, you might try changing inputs from their default value one at a time and run a simulation to see when the error happens. For example, if the only input you change is the weather file, then the error is probably caused by a problem with the weather data.

The CSP models are especially sensitive to changes in inputs.

Best regards,
Paul.

Here is the issue sir. Actually, i am doing final year project at CSP technologies. I have changed so many parameters according to my country after optimization. But, i am unable to find error. It might be in the flowrate. But, i don't know how to take flowrate based on calculations for my project. I have attached the image
Thanks
