The error is where I run the system it says that certain lines do not have flow, they don’t have direct flow in the upstream manhole because they are manholes and only for turning the system. I've tried on other, older files that I know have been run and I'm running into the same issue. I’ve also tried on other computers and having the same problem. It happens with any file I open that has a manhole with no direct flow into it. How to I let storm sewers know that certain manholes don't have direct incoming flow and ignore them. If I click okay or the X button, it shuts down storm sewers and I have to restart the program.
Thanks in advance for the help!
btw I'm running 2012 version, I've tried with 2013 but I get the same warning, but the program does not shut down. I also tried to attached the .stm file but it kept telling me it was an invalid extension for an attachment
