Geometric Network Flow Problems

Hey everyone,


I am tasked with figuring out if a geometric network would work with our company's oil and gas infrastructure data.  I am trying to make the entire nation into a network, but I am starting with a few product pipelines.  I am pretty much learning this from scratch using the online resources I can Google...


My question is regarding flow direction.  I need to make two refineries (sources) flow into one mainline. However, they keep showing as indeterminate. This is just the basic issue. I am also having trouble establishing flow direction later down the pipeline as more refineries (still sources) connect to the mainline and then are diverted at different points to distribution terminals.


Does anyone have any tips for solving this issue?


Thanks in advance for the help! I attached two pictures. The first is the flow direction issue that I am trying to resolve.  The second is the two pipeline system (Colonial in Red and Plantation in Blue) that I am trying to turn into a network. I will eventually need to (at the very least) connect the refineries (yellow) to their respective pipelines and, if possible, connect the terminals too (blue squares).
