hello everyone

i am new to ansys and hav little experience of it.
i just want to simulate a condensation problem in microchannel using fluent.
the details are given at the bottom.

i really want a guidance from any of you for this purpose.
i tried the problem but failed few times and also dont hav any idea of my failure.
please help me.
the details of my problem are:-

computational domain: rectangular microchannel of 100micrometer hydraulic diameter and length 0.03m
working fluid is R134a, operating condition is 1MPa.
mass flow inlet(492.2kg/m2s), pressure outlet and heat flux of 400KW/m2 at walls with no conduction. fluid enters in the form of superheated vapour(degree of superheat 10K)
