NSE and R Sqaure value.

[Shruti Khandelwal]

Hi everyone. 

I am facing a issue lately with the calibration part in SWATCUP. Though my calibration model has run, but it is not giving satisfactory NSE and R square values. ii haved performed several iterations with varying parameter values but each time the NSE value ranges from -0.16 to 0.00 and R sqaure is 0. i am attaching  screenshots of the latest iteration i have run. Kindly tell how do i push these value or where i am getting wroung or is these values acceptable?

Thank you in advance
