This two picture is not enough for others to know which steps are wrong. But I guess, from your pic, your parameters's setting may have some mistakes. you can re check your data and see where is wrong.

In addition to Yuyang's comment, you may also try:
1) change the fluid flow module to laminar and see if it works.
2) Use a very small value for the inlet flow and see if it works. You may use a ramp inlet, U_inlet*rm1(t), If the problem is not affected.
3) Change the solver from "Segregated" to "Fully coupled". Also make sure the Jacobian update is "On every iteration" not "Minimal".
4) Play with meshes. Sometimes, using very fine meshes near the singular points cause the solver fail to converge.
If you still get the error message, there should be something wrong with the model implementation or boundary conditions.
