I am trying to build a model of a steady flow in a collapsible tube with FSI module. I have gone through every sample models and forum threads I could find online. Based on the suggestions from Ivar I found on www.comsol.eu/community/forums/general/thread/12974/, I added the initial conditions, but it still ran out of maximum iteration of incompressible Newtonian Fluid. Also, when I tried computing the initial conditions, it didn't give me a parabolic velocity profile, but I don't think I entered the wrong equations. Could anyone please help me find out what the problem is?

Many thanks!
