Hydraflow- storm sewer program

[Anonymous]

Hello, 

 I am analyzing a pipeline using Hydraflow storm sewer program. The structure at the top left is the outfall which is a jellyfish filter. It is followed by a junction box and two grate inlets. 

When I run the analysis, there is no flow to the first pipe. The HGL starts at the pipe at the second grate inlet. I have flow values in for both pipes but for some reason, it does not take flow to the first pipe. I have attached screenshots and highlighted the section in profile view. Any help is appreciated. Thanks in advance

@Anonymous  - Can you provide more detailed on Line 3?  I see Line 1 information for your outfall, but looks like the problem is on Line 3.  Even if you sent a screen capture of the data values?

@Anonymous  - Everything seems okay with line 3.  Can you attach the .stm file so I can take a closer look?

Hello,

 When I ran the program now, I did the 'enhanced modeling system' option and now it works. I used the 'analysis w/design' option before and for some reason it did not take flow to pipe 1 before. Thank you for your time.

@Anonymous  - oh great! Glad you got it figured out!

Even though you're using a Known Q for Line 3, the program for some reason has always needed a non-zero value for the drainage area to use the Known Q's.
