error: Objective function value>=the behavioral threshold

[Ayman Al-Arag]

Hi SWAT CUP Users 

I using ArcSWAT 2009 last update , I try now to calibrate my model by using SWAT CUP 2009, after added the data of one station and when I execute calibration, and when I run the (SUFI2_post.bat) I got a message (There were no solutions with the objective function value>=the behavioral threshold) that appear in the attached file .

Note: I changed the objective function many times but also I got same message.

 

Please, I will be grateful if there is anybody guide me to solve this problem.

 

with my best regards

This is actually not an error. If you look at the message you posted it says "this is not an error". This basically means that the minimum threshold you set for your objective function was not reached. For example if you set your objective function to be Nash Sutcliffe and set the min value to be 0.5 in your "observed.txt" (under the objective function tab) but the result of your calibration only produced a Nash Sutcliffe of 0, then you will get that message. It's not that it's an error, it simply means your calibration did not do as well as you wanted it to.

i got the same issue, so we have to add simulation number? do you have any idea to fix this issue?

thanks in advance i really need help for this information.

in observed.txt you decrease the threshold value. Anyhow, you would do this if you need to do something with the behavioral solution. Normally, you don't worry about this.

0.2   : min value of objective function threshold for the behavioral solutions
