      Hello,

      I have a straight tube with a bifurcation and two outlets. At the inlet, an inlet BC is prescribed. At the oulet, windkessel BC (pressure BC) are prescribed.  If I plot the flows at inlet and outlets it seems to be okay, the outlet pressures are also as expected. The problem for me is the inlet pressure which seems a bit off. The mesh quality seems good and I am using a timestep of 0.005. What could be the problem and is this because of choosing the velocity BC (and should I just accept that the pressure is off)?

      Please can you post some images showing the flow and wall pressure? Note, I am not permitted to open attachments or follow links so post into the thread.

      I can see the graph, I was hoping for some contour plots from Fluent.
