hey guys need help in solving this question. I did attach a pic to see overview of question.

Here's the detail i put while solving this question:
SOLVER TYPE : Pressure Based
Velocity Formulation : Absolute
Time : Steady

MODEL : Laminar

MATERIAL : Water<Liquid>

BOUNDARY CONDITION : INLET- velocity magnitude = 1 m/s
gauge pressure = 100000 Pa

OUTLET - gauge pressure = 100100 Pa

**Rest are walls with default setting.

REFERENCE VALUE : COMPUTE from Inlet

SOLUTION CONTROL : pressure = 0.2
momentum = 0.6

***HYBRID INITIALIZATION

And Here's the result i am getting :

- After Initialization :

Setting Post Processing and Surfaces information ... Done.
/solve/initialize/hyb-initialization
Initialize using the hybrid initialization method.

Checking case topology...
-this case has inlets & outlets both
-pressure information is not available at the boundaries,
so it will be initialized with constant pressure

iter scalar-0

2 6.955973e-05
3 1.515677e-05
4 1.302184e-05
5 1.477042e-05
6 7.976428e-06
7 8.482481e-06
8 9.215501e-06
9 6.680556e-06
10 8.885878e-06
hybrid initialization is done.
Warning: convergence tolerance of 1.000000e-06 not reached
during Hybrid Initialization.
