Different results when running Epanet from WNTR than directly on Epanet

I'm running a 24h PDD simulation on WNTR using EpanetSimulator. I use wn.write_inpfile and save the file. When I run this saved file directly on Epanet I get different results than what I get with WNTR. You can see this discrepancy starts around 7:00 .Any Ideas what could be causing this? Thanks

It's difficult to debug without the original INP file. Can you identify differences between the original INP file and the file written by WNTR? WNTR includes a function we use for debugging to find differences (_diff_inp_files in the io.py). Also, if the original and new INP file are not in the same units, that could cause discrepancies in the results. You can set the units convention when calling write_inpfile.

Thank you and sorry I didn't react to your response before. At the end I think I managed to get similar results when I changed the time step to a smaller one.
