Mesh and convergence issue
 

I have done meshing on rectangular plates having water flow at inlet from one side and outlet on another side.when I run my analysis for 1lpm flow in CFX it runs good and converge. But for 3 lpm it is not convergeing it fluctuate in range of 10-4.i am running for steady state. Heat transfer is also there.
