In VOF model, The bubble growth matter.

In VOF model, I want to simulate boiling bubble growth.
I know that VOF model needs source in each cell for mass transfer bewteen primary(vapor) and secondary phase(liquid).
So I wrote UDF files(mass source in liquid and vapor, and energy source in mixture).
I expressed mass soures, energy source as attached image.
Fluent inputing UDF operate. but primary void fraction is zero.
I carried out this simulation.
1. Inputting mesh.
2. Activitating VOF model, Energy, laminar
3. Inputting material, UDF and assigning UDM
4. Setting boundatys, operating conditions
5. Setting initialization(Temperature : saturated temperature/fraction : 1)
6. Run after setting run calculation.
I don't undersand this matter.
I think it is the initialization matter but I don't be assured of it.
Do you think what is the matter?
Could you please help me?
