Epanet Error 303: cannot open report file

[priyanshujain01]

In my optimization work, the code is running for specific number of iterations (75) and after that it shows Epanet error 303, which means the code is unable to open report file. I am doing simple DDA and hydraulic simulation. ( no quality or PDA).
I have check my input file and also tried various changes in analysis option but still unable to work with larger iteration number.
EPANET 2.2
Python 3.7 64bit
