SWAT-CUP SUFI2 Error: Observation File Not Detected / Simulation Output Missing

[Jerome Gacu]

I am currently running a SWAT-CUP calibration using the SUFI2 algorithm and have encountered an issue that prevents the process from completing successfully. Below is a summary of the error:

Could Not Find C:\...\SUFI2.OUT\beh_*.* 

ERROR simulation number 2 in variable file 1 is missing or has a problem

 Reading goal file simulation no 2 is missing from the goal.txt file Error! simulation 1 has problems Cannot open input file /SUFI2.OUT/no_beh_sims.txt THIS IS NOT AN ERROR!! There were no solutions with the objective function value >= the behavioral threshold

What I have already tried:

• Verified that the goal.txt file exists, but seems some simulations are not listed or generated properly.

• Checked the SUFI2.OUT folder and found files like flow.out, sed_out, but not the required beh_*.* files.

• Made sure my .fig, .par, .dat and observation files are correctly formatted.

• Restarted the process multiple times with cleaned output folders.

• Followed previous guidance and tutorials, including adjusting the threshold values and observation file formats.
