SSA Error

Hi Matt,

 

I set up an existing storm sewer system and it appears that Pipes 1 and 2 are surcharging, when they should not be.  MH-01 has an external flow of 0.011 cfs, which should be the only water in both pipes.  If you can find the error, please let me know, I checked the system over and over again.  I know some inverts are not properly set, but this concerns the existing system study.  I will attached my file with this post and send it to you.  

 

Thanks,

 

Joe Komorowski

Joe -

 

I would check the Hydrodynamic Analysis Parameters of your model and review to see if you need to add a lenghtening time step or adjust the Inertial terms.
