Hybrid initialization not converging for wet steam model

  Hi,
  I have a heat exchanger model with wet steam as its working fluid, and I'm having trouble getting the hybrid initialization to converge. Has anyone had this problem before? I designed my mesh to have a y+ value less than 1 at the walls. I have a lot of CFD experience, but this is my first time using the wet steam model in Fluent.
  Thank you for your time.

  Depending on the boundary conditions the hybrid scheme may not be best suited to wet steam. Equally, if hybid initialisation doesn't fully converge it just means it's not as good as it could be and not that the model won't run. Are you trying to run both sides of the HX in one model?
