Ideally Fluent will converge in 10-15 iterations, but given the geometry changes you may need a few more. Have you run a single Fluent model in steady state and passed the pressure field over to Mechanical? The set up sounds sensible, but if the initial fluid flow field tries to expand the artery wall too much you may need to review/rethink the settings or modelling approach.Â
