While using SWMM 5.0.018, I realised that the Hotstart files don't completely eliminate instability in a fairly looped network, whereas in the latest version i.e. SWMM 5.0.022, the Hotstart files completely stabilize the same network!!!
I read the UPDATE HISTORY, but could not find exact information on what was done to archieve this. Could anyone help me identify exactly what was done to improve this feature?
