Air flow through ducts not calculating

[Anonymous]

I am designing a simple supply duct routing and have added my cfms into my grilles.  When i check the total cfms back at the units the number is not calculating to the total amount.  Instead, it appears that any transition or elbow isacting as a wall and preventing the cfms to calculate together.  Does anyone have a solution to prevent this?

It almost sounds like you have broken connections. Do you have your SOLUTION TIPS turned on? With your SOLUTION TIPS turned on, you will see an orange triangle at all unconnected object ends. SOLUTION TIPS are under your VIEW tab-MEP view. If you turn on your SOLUTION TIPS and see the triangles you'll know for sure if this is your problem.

See the attached screen shot. Also, if you have any branch duct that is not yet connected to an outlet, your airflow will not read correctly.
