I am experiencing a problem with the results of Automated FFA. For one node the FFA is equal to zero. I checked everything in the model. Everything seems to be OK. The steady pressure in that node is 51 psi. When I tried manually by assigning 22000 L/min it gives a 16 psi residual pressure. Also the iteration for that node was only one, but for the others about 3 to 5 iterations.

I advise checking the Bentley website which explains exactly what are the possible causes with the Automated FFA and the workarounds for encountered errors. Since the product requires extensive knowledge, the page I will give to you will answer these questions. Visit the Bentley FAQ page and read all the questions and answers provided to users.
