Hi
I am analyzing an existing complex sanitary system which has a diversion on the system and Harmon factor to be applied to it and surcharge to be check for the wet weather.
I prefer to go with the implicit option to calculate the diversion automatically (instead of rating curve table), but the issue is the implicit don't apply the extreme factor.
Actually there are lots of diversion structures in the system and I don't want to go with rating curve table and steady state.
Hamid,
Extreme flow factors / peaking factors are a steady state concept, typically used for pipe sizing in sewers. The implicit solver solver provides you with an unsteady simulation.
You could consider using the Implicit solver to construct the diversion rating table to use with the Convex solver, so you could then use it with the Extreme flow methods in steady state. You can read about how to do that in this article:
Modeling a flow split (diversion) with the SewerCAD or StormCAD numerical solver
Another option would be to consider using the Implicit solver with a multiplier applied to sanitary loads. You could use a new sanitary loading alternative with the scenario in question and global edit the loading information in the sanitary load control center.

Jesse,
I just used implicit to get the rating curve table and set the calculation time to 1min.
So, just select both four pipes in Mh-13, right click and went to Graph and chose Flow (first option) but seems that the incoming flow from time 0 to 0.4 hours is more!
I will appreciate you if you could help me to develop the table.
Best Regards,
Hamid
